I have devtools.editor.keymap set to "vim" and have tried going from insert mode back to command mode using ESC, CTRL-[, and CTRL-L and none of these solutions have worked. CTRL-[ changes to the devtools tab to the left, ESC opens the JS console, and CTRL-L seems to have no affect. So, how do you change from insert mode to command mode using vim keybindings in the editor?
