-# Use keyboard shortcuts to select and copy text.
-
-# Usage: put the following lines in your .Xdefaults/.Xresources:
-# URxvt.perl-ext-common: ...,keyboard-select
-# URxvt.keysym.M-Escape: perl:keyboard-select:activate
-# The following line overwrites the default Meta-s binding and allows to
-# activate keyboard-select directly in backward search mode:
-# URxvt.keysym.M-s: perl:keyboard-select:search
-
-# Use Meta-Escape to activate selection mode, then use the following keys:
-# h/j/k/l: Move cursor left/down/up/right (also with arrow keys)
-# g/G/0/^/$/H/M/L/f/F/;/,/w/W/b/B/e/E: More vi-like cursor movement keys
-# '/'/?: Start forward/backward search
-# n/N: Repeat last search, N: in reverse direction
-# Ctrl-f/b: Scroll down/up one screen
-# Ctrl-d/u: Scroll down/up half a screen
-# v/V/Ctrl-v: Toggle normal/linewise/blockwise selection
-# y/Return: Copy selection to primary buffer, Return: deactivate afterwards
-# q/Escape: Deactivate keyboard selection mode
