New xiki feature > Key shortcuts for bash/zsh

[Craig Muth]

I just did a push to github. It includes optional key shortcuts in bash and zsh.

By default, it's Ctrl+X to jump into xiki. Or if you type a command
and then type Ctrl+X, it'll expand the command in Xiki.

If you grab the latest and then want to set up the key shortcuts, run
this command and follow the steps:

$ xsh -welcome

More explanation / examples of the keys can be found here:

$ xsh --help
$ xsh --examples

Note that the expand key is now Ctrl+X (both outside and inside of
xsh) instead of Ctrl+E!
