By the way, are you aware of the keypresses that move the cursor by a word at a time? In particular, <M-Left Arrow> and <M-B> should each move backward by a word. You should be able to go <Up Arrow> <M-Left Arrow> <C-W> [type operation] <Space> <Return>. You might have to enable alt as meta key on an OS X terminal (which is obviously not the case here), or disable alt as referring to file menus on Linux (which may be the case here). Prefixing a command with ESC also works as a meta key, though I'd find it ergonomically intolerable.
