macOS Terminal cheat sheet
By Markus Wein • 369 Words
The Terminal on macOS offers quite an amount of functionality, but most of it is hard to discover unless you already know what you’re looking for. So here’s a quick cheat sheet explaining unique functions with their corresponding key combos:
Marks
Marks allow you to mark certain lines in the output, and allow you to jump between different parts of the output.
By default, every time you hit enter on your prompt, Terminal will automatically insert a mark for you. You can configure this in the Edit menu, under Marks with the option Automatically Mark Prompt Lines.
Marks are visualised in the Terminal window as light grey square brackets (They are not, however, part of the output).
* Cmd-⬆: Jump to previous mark
* Cmd-⬇: Jump to next mark
* Cmd-Shift-A: Selects the output between the current marks
* Cmd-Enter: Enter, and will always create a mark
* Cmd-Shift-Enter: Enter, but will never create a mark
* Cmd-U: Create mark
* Cmd-Shift-U: Remove mark
* Cmd-L: Clear screen to previous mark
Bookmarks
Similar to marks, they can optionally be named, and are more useful to denote larger sections of the output. They are denoted by light grey bars.
* Cmd-Shift-M: Insert Bookmark
* Cmd-Option-U: Mark current line as bookmark
* Cmd-Shift-Option-M: Insert named bookmark
* Cmd-Option-⬆: Jump to previous bookmark
* Cmd-Option-⬇: Jump to next bookmark
* Cmd-Option-L: Clear to previous bookmark
Panes
View different parts of the scrollback buffer of the same terminal.
* Cmd-D: Split window into panes
* Cmd-Shift-D: close split pane
Miscellaneous
* Cmd-K: Clear everything
* Cmd-Option-K: Clear scroll back (everything except what you see on the screen)
* Cmd-Option-O: Toggle use of option as meta key
* Cmd-Ctrl-V: Paste escaped text. Useful for pasting e.g. paths containing whitespace.
* Cmd-Shift-Option-C: Copy as plain text
* Cmd-Option-PageUp or PageDown: Scroll one line up/down
* Cmd-[ or ]: Switch between windows
* Cmd-Shift-[ or ]: Switch between tabs
