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.

1360menuBar
1361 The exact syntax used is *almost* solidified. In the menus, DON'T try to
1362 use menuBar commands that add or remove a menuBar.
1363
1364 Note that in all of the commands, the */path/* *cannot* be omitted: use
1365 ./ to specify a menu relative to the current menu.
1366
1367 Overview of menuBar operation
1368 For the menuBar XTerm escape sequence "ESC ] 703 ; Pt ST", the syntax of
1369 "Pt" can be used for a variety of tasks:
1370
1371 At the top level is the current menuBar which is a member of a circular
1372 linked-list of other such menuBars.
1373
1374 The menuBar acts as a parent for the various drop-down menus, which in
1375 turn, may have labels, separator lines, menuItems and subMenus.
1376
1377 The menuItems are the useful bits: you can use them to mimic keyboard
1378 input or even to send text or escape sequences back to rxvt.
1379
1380 The menuBar syntax is intended to provide a simple yet robust method of
1381 constructing and manipulating menus and navigating through the menuBars.
1382
1383 The first step is to use the tag [menu:*name*] which creates the menuBar
1384 called *name* and allows access. You may now or menus, subMenus, and
1385 menuItems. Finally, use the tag [done] to set the menuBar access as
1386 readonly to prevent accidental corruption of the menus. To re-access the
1387 current menuBar for alterations, use the tag [menu], make the
1388 alterations and then use [done]
1389
1390
1391
1392 Commands
1393 [menu:+*name*]
1394 access the named menuBar for creation or alteration. If a new
1395 menuBar is created, it is called *name* (max of 15 chars) and the
1396 current menuBar is pushed onto the stack
1397
1398 [menu]
1399 access the current menuBar for alteration
1400
1401 [title:+*string*]
1402 set the current menuBar's title to *string*, which may contain the
1403 following format specifiers:
1404
1405 B<%n> rxvt name (as per the B<-name> command-line option)
1406 B<%v> rxvt version
1407 B<%%> literal B<%> character
1408
1409 [done]
1410 set menuBar access as readonly. End-of-file tag for [read:+*file*]
1411 operations.
1412
1413 [read:+*file*]
1414 read menu commands directly from *file* (extension ".menu" will be
1415 appended if required.) Start reading at a line with [menu] or
1416 [menu:+*name* and continuing until [done] is encountered.
1417
1418 Blank and comment lines (starting with #) are ignored. Actually,
1419 since any invalid menu commands are also ignored, almost anything
1420 could be construed as a comment line, but this may be tightened up
1421 in the future ... so don't count on it!.
1422
1423 [read:+*file*;+*name*]
1424 The same as [read:+*file*], but start reading at a line with
1425 [menu:+*name*] and continuing until [done:+*name*] or [done] is
1426 encountered.
1427
1428 [dump]
1429 dump all menuBars to the file /tmp/rxvt-PID in a format suitable for
1430 later rereading.
1431
1432 [rm:name]
1433 remove the named menuBar
1434
1435 [rm] [rm:]
1436 remove the current menuBar
1437
1438 [rm*] [rm:*]
1439 remove all menuBars
1440
1441 [swap]
1442 swap the top two menuBars
1443
1444 [prev]
1445 access the previous menuBar
1446
1447 [next]
1448 access the next menuBar
1449
1450 [show]
1451 Enable display of the menuBar
1452
1453 [hide]
1454 Disable display of the menuBar
1455
1456 [pixmap:+*name*]
1457 [pixmap:+*name*;*scaling*]
1458 (set the background pixmap globally
1459
1460 A Future implementation *may* make this local to the menubar)
1461
1462 [:+*command*:]
1463 ignore the menu readonly status and issue a *command* to or a menu
1464 or menuitem or change the ; a useful shortcut for setting the quick
1465 arrows from a menuBar.
1466
1467
1468
1469 Adding and accessing menus
1470 The following commands may also be + prefixed.
1471
1472 /+ access menuBar top level
1473
1474 ./+ access current menu level
1475
1476 ../+
1477 access parent menu (1 level up)
1478
1479 ../../
1480 access parent menu (multiple levels up)
1481
1482 */path/*menu
1483 add/access menu
1484
1485 */path/*menu/*
1486 add/access menu and clear it if it exists
1487
1488 */path/*{-}
1489 add separator
1490
1491 */path/*{item}
1492 add item as a label
1493
1494 */path/*{item} action
1495 add/alter *menuitem* with an associated *action*
1496
1497 */path/*{item}{right-text}
1498 add/alter *menuitem* with right-text as the right-justified text and
1499 as the associated *action*
1500
1501 */path/*{item}{rtext} action
1502 add/alter *menuitem* with an associated *action* and with rtext as
1503 the right-justified text.
1504
1505 Special characters in *action* must be backslash-escaped:
1506 \a \b \E \e \n \r \t \octal
1507
1508 or in control-character notation:
1509 ^@, ^A .. ^Z .. ^_, ^?
1510
1511 To send a string starting with a NUL (^@) character to the program,
1512 start *action* with a pair of NUL characters (^@^@), the first of which
1513 will be stripped off and the balance directed to the program. Otherwise
1514 if *action* begins with NUL followed by non-+NUL characters, the leading
1515 NUL is stripped off and the balance is sent back to rxvt.
1516
1517 As a convenience for the many Emacs-type editors, *action* may start
1518 with M- (eg, M-$ is equivalent to \E$) and a CR will be appended if
1519 missed from M-x commands.
1520
1521 As a convenience for issuing XTerm ESC ] sequences from a menubar (or
1522 quick arrow), a BEL (^G) will be appended if needed.
1523
1524 For example,
1525 M-xapropos is equivalent to \Exapropos\r
1526
1527 and \E]703;mona;100 is equivalent to \E]703;mona;100\a
1528
1529 The option {*right-rtext*} will be right-justified. In the absence of a
1530 specified action, this text will be used as the *action* as well.
1531
1532 For example,
1533 /File/{Open}{^X^F} is equivalent to /File/{Open}{^X^F} ^X^F
1534
1535 The left label *is* necessary, since it's used for matching, but
1536 implicitly hiding the left label (by using same name for both left and
1537 right labels), or explicitly hiding the left label (by preceeding it
1538 with a dot), makes it possible to have right-justified text only.
1539
1540 For example,
1541 /File/{Open}{Open} Open-File-Action
1542
1543 or hiding it
1544 /File/{.anylabel}{Open} Open-File-Action
1545

1559 remove separator)
1560
1561 -/path/menu/*
1562 remove all items, separators and submenus from menu
1563
1564
1565
1566 Quick Arrows
1567 The menus also provide a hook for *quick arrows* to provide easier user
1568 access. If nothing has been explicitly set, the default is to emulate
1569 the curror keys. The syntax permits each arrow to be altered
1570 individually or all four at once without re-entering their common
1571 beginning/end text. For example, to explicitly associate cursor actions
1572 with the arrows, any of the following forms could be used:
1573
1574 <r>+*Right*
1575 <l>+*Left*
1576 <u>+*Up*
1577 <d>+*Down*
1578 Define actions for the respective arrow buttons
1579
1580 <b>+*Begin*
1581 <e>+*End*
1582 Define common beginning/end parts for *quick arrows* which used in
1583 conjunction with the above <r> <l> <u> <d> constructs
1584
1585 For example, define arrows individually,
1586 <u>\E[A
1587
1588 <d>\E[B
1589
1590 <r>\E[C
1591
1592 <l>\E[D
1593
1594 or all at once
1595 <u>\E[AZ<><d>\E[BZ<><r>\E[CZ<><l>\E[D
1596
1597 or more compactly (factoring out common parts)
