Commands

helm-M-x, which by default is bound to <helm-prefix> M-x, is used to launch commands in Helm. For convenience, you should bind it to M-x.

Features include:

• Smart sorting
• Show key bindings next to command names
• Show documentation with persistent action (C-z)
• Show prefix arguments in the mode line

Prefix arguments with helm-M-x

Prefix arguments must be passed after calling helm-M-x. Simply type the prefix you want (e.g. C-u or M-9) on the highlighted command before hitting RET to execute it.

This allows you to view the command’s documentation (with persistent action) and know exactly what prefix arguments do before passing them.

To put the command in the minibuffer, hit C-c C-y on the highlighted command.
