iterm2 is a great terminal in Mac OS X. It has a lot of features
go beyond what you thought a terminal might be. here is a tip I
learned recently.

Turns out you can select text without mouse in iterm2. just by
press CMD-f to activate find. Enter some initial text you wish to
copy, you’ll find that the last matching highlighted with selected state. use CMD-G or CMD-Shift-G to switch selected text as you want and then press tab to advanced the selected text by words. To advance the beginning of the selection to the left, press Shift-tab. At most one line of text can be selected this way.

It’s up to you to say if this is useful or not.
