I usually use Linux, no expert at all (very far from it) but I use it daily.
Sometimes I find myself using (someone else's) Mac and typing commands into a Terminal.
In Linux, I can use Ctrl+Left and Ctrl+Right to move backward or forward in the current line one word at a time (as in most text editors btw). If I try to do that in Mac OS, it switches workspaces, or brings to front another window, or some irritating thing like that. I think I tried both the Command and the Ctrl (proper) key.
Is there a different key combination for that in Mac OS? At the end I find myself holding down the arrow kay to move one character at a time, which in Mac OS for some reason is like 10 times slower than in Linux and Windows.
