Single keys
can be made to execute commands when the cursor is at the
beginning of a headline, i.e. before the first star. Configure
the variable org-use-speed-commands to activate this
feature. There is a pre-defined list of commands, and you can add
more such commands using the variable
org-speed-commands-user. Speed keys do not only
speed up navigation and other commands, but they also provide an
alternative way to execute commands bound to keys that are not or
not easily available on a TTY, or on a small mobile device with a
limited keyboard.
To see which commands are available, activate the feature and press ? with the cursor at the beginning of a headline.
