Use

Command line

Type : and a command, as in Vim.

Using it

: opens a prompt. It lists the commands that start with what you typed. Enter runs the highlighted one (an exact match comes first), <C-y> completes the name, Esc closes.

Commands

Command	Action
`:q` `:quit` `:wq` `:x` `:bd` `:tabc` `:tabclose`	close the tab
`:qa` `:qall` `:wqa` `:xa`	quit Lean; the session is saved
`:w` `:write`	save the session
`:e` `:edit` `:o` `:open`	open; with an address or search text it goes there directly
`:tabnew` `:tabe` `:tabedit` `:t`	the same in a new tab
`:tabn` `:bn` / `:tabp` `:bp`	next, previous tab
`:b` `:ls` `:buffers` `:tabs`	search tabs
`:u` `:undo`	reopen the closed tab
`:sp` `:split` / `:vs` `:vsplit`	split down, split right
`:close` / `:on` `:only`	close this pane, close the other panes
`:set` / `:so` `:source`	settings, reload the config
`:colo` `:colorscheme`	another theme
`:reload` `:back` `:forward` `:y` `:yank`	reload, back, forward, copy the address
`:devtools` `:console` `:restart`	developer tools, console, restart the tab
`:pass` `:totp` `:passbolt`	fill login, fill one-time code, Passbolt hand-off
`:kittens`	kittens, for 5 seconds

Every action also works under its own name, for example :foldAll.

Your own commands

Add them under commands in config.json. The value is an action; for open and openNewTab an address may follow, and %s in it stands for what you type after the command.

"commands": {
  "q": "quit",
  "issue": "openNewTab https://example.atlassian.net/browse/%s",
  "mail": "openNewTab https://mail.example.com/",
  "bd": "none"
}

With this, :issue WEB-214 opens that issue in a new tab, :q quits Lean instead of closing the tab, and :bd does nothing.
