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

1334menuBar
1335 The exact syntax used is *almost* solidified. In the menus, DON'T try to
1336 use menuBar commands that add or remove a menuBar.
1337
1338 Note that in all of the commands, the */path/* *cannot* be omitted: use
1339 ./ to specify a menu relative to the current menu.
1340
1341 Overview of menuBar operation
1342 For the menuBar XTerm escape sequence "ESC ] 703 ; Pt ST", the syntax of
1343 "Pt" can be used for a variety of tasks:
1344
1345 At the top level is the current menuBar which is a member of a circular
1346 linked-list of other such menuBars.
1347
1348 The menuBar acts as a parent for the various drop-down menus, which in
1349 turn, may have labels, separator lines, menuItems and subMenus.
1350
1351 The menuItems are the useful bits: you can use them to mimic keyboard
1352 input or even to send text or escape sequences back to rxvt.
1353
1354 The menuBar syntax is intended to provide a simple yet robust method of
1355 constructing and manipulating menus and navigating through the menuBars.
1356
1357 The first step is to use the tag [menu:*name*] which creates the menuBar
1358 called *name* and allows access. You may now or menus, subMenus, and
1359 menuItems. Finally, use the tag [done] to set the menuBar access as
1360 readonly to prevent accidental corruption of the menus. To re-access the
1361 current menuBar for alterations, use the tag [menu], make the
1362 alterations and then use [done]
1363
1364
1365
1366 Commands
1367 [menu:+*name*]
1368 access the named menuBar for creation or alteration. If a new
1369 menuBar is created, it is called *name* (max of 15 chars) and the
1370 current menuBar is pushed onto the stack
1371
1372 [menu]
1373 access the current menuBar for alteration
1374
1375 [title:+*string*]
1376 set the current menuBar's title to *string*, which may contain the
1377 following format specifiers:
1378
1379 B<%n> rxvt name (as per the B<-name> command-line option)
1380 B<%v> rxvt version
1381 B<%%> literal B<%> character
1382
1383 [done]
1384 set menuBar access as readonly. End-of-file tag for [read:+*file*]
1385 operations.
1386
1387 [read:+*file*]
1388 read menu commands directly from *file* (extension ".menu" will be
1389 appended if required.) Start reading at a line with [menu] or
1390 [menu:+*name* and continuing until [done] is encountered.
1391
1392 Blank and comment lines (starting with #) are ignored. Actually,
1393 since any invalid menu commands are also ignored, almost anything
1394 could be construed as a comment line, but this may be tightened up
1395 in the future ... so don't count on it!.
1396
1397 [read:+*file*;+*name*]
1398 The same as [read:+*file*], but start reading at a line with
1399 [menu:+*name*] and continuing until [done:+*name*] or [done] is
1400 encountered.
1401
1402 [dump]
1403 dump all menuBars to the file /tmp/rxvt-PID in a format suitable for
1404 later rereading.
1405
1406 [rm:name]
1407 remove the named menuBar
1408
1409 [rm] [rm:]
1410 remove the current menuBar
1411
1412 [rm*] [rm:*]
1413 remove all menuBars
1414
1415 [swap]
1416 swap the top two menuBars
1417
1418 [prev]
1419 access the previous menuBar
1420
1421 [next]
1422 access the next menuBar
1423
1424 [show]
1425 Enable display of the menuBar
1426
1427 [hide]
1428 Disable display of the menuBar
1429
1430 [pixmap:+*name*]
1431 [pixmap:+*name*;*scaling*]
1432 (set the background pixmap globally
1433
1434 A Future implementation *may* make this local to the menubar)
1435
1436 [:+*command*:]
1437 ignore the menu readonly status and issue a *command* to or a menu
1438 or menuitem or change the ; a useful shortcut for setting the quick
1439 arrows from a menuBar.
1440
1441
1442
1443 Adding and accessing menus
1444 The following commands may also be + prefixed.
1445
1446 /+ access menuBar top level
1447
1448 ./+ access current menu level
1449
1450 ../+
1451 access parent menu (1 level up)
1452
1453 ../../
1454 access parent menu (multiple levels up)
1455
1456 */path/*menu
1457 add/access menu
1458
1459 */path/*menu/*
1460 add/access menu and clear it if it exists
1461
1462 */path/*{-}
1463 add separator
1464
1465 */path/*{item}
1466 add item as a label
1467
1468 */path/*{item} action
1469 add/alter *menuitem* with an associated *action*
1470
1471 */path/*{item}{right-text}
1472 add/alter *menuitem* with right-text as the right-justified text and
1473 as the associated *action*
1474
1475 */path/*{item}{rtext} action
1476 add/alter *menuitem* with an associated *action* and with rtext as
1477 the right-justified text.
1478
1479 Special characters in *action* must be backslash-escaped:
1480 \a \b \E \e \n \r \t \octal
1481
1482 or in control-character notation:
1483 ^@, ^A .. ^Z .. ^_, ^?
1484
1485 To send a string starting with a NUL (^@) character to the program,
1486 start *action* with a pair of NUL characters (^@^@), the first of which
1487 will be stripped off and the balance directed to the program. Otherwise
1488 if *action* begins with NUL followed by non-+NUL characters, the leading
1489 NUL is stripped off and the balance is sent back to rxvt.
1490
1491 As a convenience for the many Emacs-type editors, *action* may start
1492 with M- (eg, M-$ is equivalent to \E$) and a CR will be appended if
1493 missed from M-x commands.
1494
1495 As a convenience for issuing XTerm ESC ] sequences from a menubar (or
1496 quick arrow), a BEL (^G) will be appended if needed.
1497
1498 For example,
1499 M-xapropos is equivalent to \Exapropos\r
1500
1501 and \E]703;mona;100 is equivalent to \E]703;mona;100\a
1502
1503 The option {*right-rtext*} will be right-justified. In the absence of a
1504 specified action, this text will be used as the *action* as well.
1505
1506 For example,
1507 /File/{Open}{^X^F} is equivalent to /File/{Open}{^X^F} ^X^F
1508
1509 The left label *is* necessary, since it's used for matching, but
1510 implicitly hiding the left label (by using same name for both left and
1511 right labels), or explicitly hiding the left label (by preceeding it
1512 with a dot), makes it possible to have right-justified text only.
1513
1514 For example,
1515 /File/{Open}{Open} Open-File-Action
1516
1517 or hiding it
1518 /File/{.anylabel}{Open} Open-File-Action
1519

1534
1535 -/path/menu/*
1536 remove all items, separators and submenus from menu
1537
1538
1539
1540 Quick Arrows
1541 The menus also provide a hook for *quick arrows* to provide easier user
1542 access. If nothing has been explicitly set, the default is to emulate
1543 the curror keys. The syntax permits each arrow to be altered
1544 individually or all four at once without re-entering their common
1545 beginning/end text. For example, to explicitly associate cursor actions
1546 with the arrows, any of the following forms could be used:
