Keybindings
Editora ships five keymaps; pick one below. Emacs is the default; you can switch to any of them (or rebind any command) in Settings → Keymaps. Every binding maps to a command, so the same actions are also reachable from the M-x palette (see the full command list).
C- Control M- Alt / Option (Meta) S- Shift Space-separated = a chord sequence, e.g. C-x then C-s
macOS: the CUA, Sublime Text, VS Code, and IntelliJ keymaps use ⌘ (Command) wherever the tables above show C- (Control). In the Emacs keymap, the Option dead keys (Option+e/i/u/n/`) are intercepted by the OS for accent composition, so a few M- chords like M-e aren't reachable by keyboard there. The command palette still works.
