for Keyboard Shortcuts in Applet for Improved User Experience

[abhiyandhakal]

Is your feature request related to a problem? Please describe.
In the pre-release version of 1.0.0, you can perform various tasks by clicking on the applet. But I feel really bothered to click the applet instead of having some shortcuts to do that.

Describe the solution you'd like
Commands like

• power-menu toggle should toggle menu hidden and visible state.
• power-menu settings should open up the settings.

I can bind these commands.

Describe alternatives you've considered
As alternative solutions, I have considered having the keyboard shortcuts settings in the settings itself. This could be a good solution, but I don't know how to do it.
