Typing the current date ( or any string ) via a shortcut as if the keys had been actually typed with the hardware keyboard in any application.
That works in all softs, CLI or GUI... I don't want to waste time to all the time typing the same stuff . So, I have that command in my window manager shortcuts ( meta+l ). All the window managers have editable shortcuts AFAIK. If not, or you don't want to use it that way, you can easily use the xbindkeys soft. I you're using kde4, you can run : $ systemsettings then open "inputs actions" and create a new shortcut. For Gnome take a look there : http://www.cyberciti.biz/faq/howto-create-keyboard-shortcuts-in-gnome/ A more advanced one, with strings and newlines : $ xvkbd -xsendevent -text "---8

Change every instance of OLD to NEW in file FILE

diff the same file in two directories.
This is useful when you're diffing two files of the same name in radically different directory trees. For example: Set $ path1='/some/long/convoluted/path/to/all/of/your/source/from/a/long/dead/machine' then $ path2='/local/version/of/same/file' then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.
