01 — Playback
The six you will use constantly
Spacebar starts and stops playback. R starts recording. Return sends the playhead back to the beginning.
C toggles the cycle region, which loops a section. This is the one people underuse: set a cycle around an edit and let it repeat while you adjust, rather than pressing play again and again.
The left and right arrow keys nudge the playhead. Hold Shift with them to move in larger steps.
K toggles the metronome, which is worth knowing mainly so you can turn it off, because it is on by default and unhelpful for speech.
C before every export as well as during editing. A cycle region left on is the most common cause of a truncated export.
02 — Editing
The ones that make cutting fast
Command and T splits the selected region at the playhead. This is the most important shortcut in the program for anyone editing speech.
Command and J joins selected regions back together. Command and D duplicates a region, useful for repeating a section of music.
Command and Z undoes, and Command and Shift and Z redoes. Worth naming because GarageBand's undo history is deeper than people expect, and it is often faster to undo several steps than to repair one.
Command and A selects everything, which combined with Command and T is how you cut every track at the same point and keep a multi-person recording aligned.
03 — Navigation
Zoom, which matters more than it sounds
Command and right arrow zooms in. Command and left arrow zooms out. Z zooms to fit your selection, and pressing it again returns to where you were.
Editing speech means moving between a whole-file view and a close view hundreds of times per session. Doing that with the zoom slider is the single biggest time sink for people who have not learned these.
Control and arrow keys change track height, which helps when you have more tracks than fit on screen.
04 — The single letters
Panel toggles nobody finds by accident
B opens Smart Controls, where the voice presets and effect settings live. E opens the editor, where region gain, fades and Flex Time are. A shows automation on the selected track.
Y opens the Library of track presets. F opens the media browser. X opens the mixer.
These are genuinely hard to discover because they are plain single letters with no modifier, and the menus do not always advertise them. B, E and A are the three worth memorising first.
Learn B, E and A this week and ignore the rest. Three shortcuts used constantly beat twenty you have to think about.
05 — Making your own
Command Editor, and knowing when to stop
GarageBand does not expose the full key command editor that Logic Pro does, so customisation is limited. macOS lets you assign a shortcut to any menu item through System Settings, Keyboard, Keyboard Shortcuts, App Shortcuts, which covers most of what you might want.
Type the menu item's name exactly as it appears, including capitalisation, or it will not bind.
Worth being honest about the ceiling, though. Shortcuts make GarageBand faster; they do not remove the fact that closing every gap after a delete is manual, and that finding filler words means listening to the whole recording.
If the goal is editing a weekly conversation quickly, the gain from better shortcuts is smaller than the gain from a tool that edits speech as text. Hilite does that and we make it, so weigh it as you like.
