# Tabbed perl extension for rxvt-unicode terminal emulator.
|
||||
# Modified by Roman Dobosz <gryf73 at gmail do com>

# 2008-08-22 18:01:55
|
||||
# - Modified shortcuts for tab navigation - now it uses shift + left/right
|
||||
# arrow to navigate, also creating new shell is changed to CTRL+Shift+n.
|
||||
# - Added shortcuts to move tab between others witch CTRL left/right arrow
|
||||
# - Added some predefinied actions - CTRL+Shift+r for "su -" command and
|
||||
# CTRL+Shift+m for "mc" and other like named ssh sessions.
|
||||
# - Added labels for custom shells (like "root", "mc" and so on)
|
||||
#
|
||||
# Please note, I don't know Perl!
|
||||
#
|
||||
# 2009-11-23 11:11:19
|
||||
# - Added shortcuts for apps with Mod4 key (mutt as an example)
|
||||
#
|
||||
# 2009-11-23 13:25:13
|
||||
# - Merged activity indicator from
|
||||
# http://mina86.com/2009/05/16/tabbed-urxvt-extension/#more but without
|
||||
# changes on tabs (like adding term title just behind all tabs). New resources
|
||||
# can be use to change defaults (as in original solution):
|
||||
# - tabbed-timeouts with format:
|
||||
# (<timeout> ":" <character> ":")* <timeout> ":" <character> ":"
|
||||
# default '16:.:8:::4:+'. Asterisk is always present as a first indicator
|
||||
# character, just like in original tabbed extension.
|
||||
# - new-button, default to 'true'. Used to disable [NEW] button.
|
||||
#
|
||||
# 2009-11-24 23:34:51
|
||||
# - Added possibility to quickswitch between first ten tabs with predefinied
|
||||
# combination of CTRL+1..0 keys, which will activate proper tab.
|
||||
# - Added possibility to remove numbers from tab names by setting resource
|
||||
# tab-numbers to false.
|
||||
#
|
||||
# 2009-11-25 21:40:30
|
||||
# - Added colors for tabs, which have activity on them. First is to be set when
|
||||
# first activity (active-fg, defaults to red) appear on inactive tab. Last one
|
||||
# (actived-fg, blue by default) is set when there is no more possible timeouts.
|
||||
# Third one (actives-fg, purple) is set on all in between of these two.
