Lem manual (EN)

Lem has Emacs-like keybindings, as well as a vi emulation (M-x vi-mode).

So, to open a file, press C-x C-f (you get the file selection dialog shown above). To save it, it's C-x C-s.

To switch to the REPL: C-c C-z.

To compile and load a buffer: C-c C-k. To compile a function: C-c C-c.

To switch windows: C-x o. To make a window fullscreen: C-x 1. To split it vertically: C-x 3 and horizontally: C-x 2.

To switch buffers: C-x b.

To run an interactive command: M-x (alt-x).
