		1094	The spelling of I<key> depends on your implementation of X. An easy way to

		1115
		1116	If the I<action> starts with C<string:> (or otherwise contains no colons),
		1117	then the remaining C<STRING> will be passed to the program running in the
		1118	terminal. For example, you could replace whatever Shift-Tab outputs by the
		1119	string C<echo rm -rf /> followed by a newline:
		1120
		1121	URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
		1122
		1123	This could in theory be used to completely redefine your keymap.
		1124
		1125	In addition, for actions of this type, you can define a range of
		1126	keysyms in one shot by loading the C<keysym-list> perl extension and
		1127	providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
