22FREQUENTLY ASKED QUESTIONS 22FREQUENTLY ASKED QUESTIONS
23 The new selection selects pieces that are too big, how can I select
24 single words?
25 Yes. For example, if you want to select alphanumeric words, you can
26 use the following resource:
27
28 URxvt.selection.pattern-0: ([[:word:]]+)
29
30 If you click more than twice, the selection will be extended more
31 and more.
32
33 To get a selection that is very similar to the old code, try this
34 pattern:
35
36 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
37
38 Please also note that the *LeftClick Shift-LeftClik* combination
39 also selects words like the old code.
40
41 I don't like the new selection/popups/hotkeys/perl, how do I
42 change/disable it?
43 You can disable the perl extension completely by setting the
44 perl-ext-common resource to the empty string, which also keeps
45 rxvt-unicode from initialising perl, saving memory.
46
47 If you only want to disable specific features, you first have to
48 identify which perl extension is responsible. For this, read the
49 section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
50 example, to disable the selection-popup and option-popup, specify
51 this perl-ext-common resource:
52
53 URxvt.perl-ext-common: default,-selection-popup,-option-popup
54
55 This will keep the default extensions, but disable the two popup
56 extensions. Some extensions can also be configured, for example,
57 scrollback search mode is triggered by M-s. You can move it to any
58 other combination either by setting the searchable-scrollback
59 resource:
60
61 URxvt.searchable-scrollback: CM-s
62
23 Isn't rxvt supposed to be small? Don't all those features bloat? 63 Isn't rxvt supposed to be small? Don't all those features bloat?

198 privileges immediately. This is much safer than most other terminals
199 that keep privileges while running (but is more relevant to urxvt,

1338menuBar
1339 The exact syntax used is *almost* solidified. In the menus, DON'T try to
1340 use menuBar commands that add or remove a menuBar.
1341
1342 Note that in all of the commands, the */path/* *cannot* be omitted: use
1343 ./ to specify a menu relative to the current menu.
1344
1345 Overview of menuBar operation
1346 For the menuBar XTerm escape sequence "ESC ] 703 ; Pt ST", the syntax of
1347 "Pt" can be used for a variety of tasks:
1348
1349 At the top level is the current menuBar which is a member of a circular
1350 linked-list of other such menuBars.
1351
1352 The menuBar acts as a parent for the various drop-down menus, which in
1353 turn, may have labels, separator lines, menuItems and subMenus.
1354
1355 The menuItems are the useful bits: you can use them to mimic keyboard
1356 input or even to send text or escape sequences back to rxvt.
1357
1358 The menuBar syntax is intended to provide a simple yet robust method of
1359 constructing and manipulating menus and navigating through the menuBars.
1360
1361 The first step is to use the tag [menu:*name*] which creates the menuBar
1362 called *name* and allows access. You may now or menus, subMenus, and
1363 menuItems. Finally, use the tag [done] to set the menuBar access as
1364 readonly to prevent accidental corruption of the menus. To re-access the
1365 current menuBar for alterations, use the tag [menu], make the
1366 alterations and then use [done]
1367
1368
1369
1370 Commands
1371 [menu:+*name*]
1372 access the named menuBar for creation or alteration. If a new
1373 menuBar is created, it is called *name* (max of 15 chars) and the
1374 current menuBar is pushed onto the stack
1375
1376 [menu]
1377 access the current menuBar for alteration
1378
1379 [title:+*string*]
1380 set the current menuBar's title to *string*, which may contain the
1381 following format specifiers:
1382
1383 B<%n> rxvt name (as per the B<-name> command-line option)
1384 B<%v> rxvt version
1385 B<%%> literal B<%> character
1386
1387 [done]
1388 set menuBar access as readonly. End-of-file tag for [read:+*file*]
1389 operations.
1390
1391 [read:+*file*]
1392 read menu commands directly from *file* (extension ".menu" will be
1393 appended if required.) Start reading at a line with [menu] or
1394 [menu:+*name* and continuing until [done] is encountered.
1395
1396 Blank and comment lines (starting with #) are ignored. Actually,
1397 since any invalid menu commands are also ignored, almost anything
1398 could be construed as a comment line, but this may be tightened up
1399 in the future ... so don't count on it!.
1400
1401 [read:+*file*;+*name*]
1402 The same as [read:+*file*], but start reading at a line with
1403 [menu:+*name*] and continuing until [done:+*name*] or [done] is
1404 encountered.
1405
1406 [dump]
1407 dump all menuBars to the file /tmp/rxvt-PID in a format suitable for
1408 later rereading.
1409
1410 [rm:name]
1411 remove the named menuBar
1412
1413 [rm] [rm:]
1414 remove the current menuBar
1415
1416 [rm*] [rm:*]
1417 remove all menuBars
1418
1419 [swap]

1421
1422 [prev]
1423 access the previous menuBar
1424
1425 [next]
1426 access the next menuBar
1427
1428 [show]
1429 Enable display of the menuBar
1430
1431 [hide]
1432 Disable display of the menuBar

1435 [pixmap:+*name*;*scaling*]
1436 (set the background pixmap globally
1437
1438 A Future implementation *may* make this local to the menubar)
1439
1440 [:+*command*:]
1441 ignore the menu readonly status and issue a *command* to or a menu
1442 or menuitem or change the ; a useful shortcut for setting the quick
1443 arrows from a menuBar.
1444
1445
1446
1447 Adding and accessing menus
1448 The following commands may also be + prefixed.
1449
1450 /+ access menuBar top level
1451
1452 ./+ access current menu level
1453
1454 ../+
1455 access parent menu (1 level up)
1456
1457 ../../
1458 access parent menu (multiple levels up)
1459
1460 */path/*menu
1461 add/access menu
1462
1463 */path/*menu/*
1464 add/access menu and clear it if it exists
1465
1466 */path/*{-}
1467 add separator
1468
1469 */path/*{item}
1470 add item as a label
1471
1472 */path/*{item} action
1473 add/alter *menuitem* with an associated *action*
1474
1475 */path/*{item}{right-text}
1476 add/alter *menuitem* with right-text as the right-justified text and
1477 as the associated *action*
1478
1479 */path/*{item}{rtext} action
1480 add/alter *menuitem* with an associated *action* and with rtext as
1481 the right-justified text.
1482
1483 Special characters in *action* must be backslash-escaped:
1484 \a \b \E \e \n \r \t \octal
1485
1486 or in control-character notation:
1487 ^@, ^A .. ^Z .. ^_, ^?
1488
1489 To send a string starting with a NUL (^@) character to the program,
1490 start *action* with a pair of NUL characters (^@^@), the first of which
1491 will be stripped off and the balance directed to the program. Otherwise
1492 if *action* begins with NUL followed by non-+NUL characters, the leading
1493 NUL is stripped off and the balance is sent back to rxvt.
1494
1495 As a convenience for the many Emacs-type editors, *action* may start
1496 with M- (eg, M-$ is equivalent to \E$) and a CR will be appended if
1497 missed from M-x commands.
1498
1499 As a convenience for issuing XTerm ESC ] sequences from a menubar (or
1500 quick arrow), a BEL (^G) will be appended if needed.
1501
1502 For example,
1503 M-xapropos is equivalent to \Exapropos\r
1504
1505 and \E]703;mona;100 is equivalent to \E]703;mona;100\a
1506
1507 The option {*right-rtext*} will be right-justified. In the absence of a
1508 specified action, this text will be used as the *action* as well.
1509
1510 For example,
1511 /File/{Open}{^X^F} is equivalent to /File/{Open}{^X^F} ^X^F
1512
1513 The left label *is* necessary, since it's used for matching, but
1514 implicitly hiding the left label (by using same name for both left and
1515 right labels), or explicitly hiding the left label (by preceeding it
1516 with a dot), makes it possible to have right-justified text only.
1517
1518 For example,
1519 /File/{Open}{Open} Open-File-Action
1520
1521 or hiding it
1522 /File/{.anylabel}{Open} Open-File-Action

1540 remove all items, separators and submenus from menu
1541
1542
1543
1544 Quick Arrows
1545 The menus also provide a hook for *quick arrows* to provide easier user
1546 access. If nothing has been explicitly set, the default is to emulate
1547 the curror keys. The syntax permits each arrow to be altered
1548 individually or all four at once without re-entering their common
1549 beginning/end text. For example, to explicitly associate cursor actions
1550 with the arrows, any of the following forms could be used:
1551
1552 <r>+*Right*
1553 <l>+*Left*
1554 <u>+*Up*
1555 <d>+*Down*
1556 Define actions for the respective arrow buttons
1557
1558 <b>+*Begin*
1559 <e>+*End*
1560 Define common beginning/end parts for *quick arrows* which used in
1561 conjunction with the above <r> <l> <u> <d> constructs
1562
1563 For example, define arrows individually,
1564 <u>\E[A
1565
1566 <d>\E[B
1567
