Bracket keys resize the brush ([ and ]) on every layout, but with a non-Latin input method active some other shortcuts stop responding.
Reading the key names
- Keys joined by + are pressed together: Ctrl+Shift+P means hold Ctrl and Shift, then P.
- On a Mac, Cmd is ⌘, Option is ⌥ (labelled Alt on some keyboards), Control is ⌃ and Shift is ⇧.
- Windows Ctrl usually becomes Cmd on a Mac, but not always — this reference lists both combinations separately.
- With a Korean, Japanese or Chinese input method active, shortcuts built on letter keys may not fire. Switch to Latin input and try again.
- When a combination does nothing, another program has often claimed it as a global shortcut first.
