NoteTrace works well from the keyboard. Press ? anywhere in the notes list to see every shortcut, or open Settings, Appearance, Keyboard Shortcuts, View.
Single-key shortcuts only work when you're not typing in a field. Turn them off on a device with the switch in Settings, Appearance, Keyboard Shortcuts (the ? sheet and Ctrl+K still work).
In a text note, type / at the start of a line or after a space. A menu of commands opens; keep typing to filter it, use the arrow keys, and press Enter. Esc closes the menu without closing the note.
