Make the description shortcut inserter more obvious to users

[mvdicarlo]

Currently the shortcut insert key is somewhat random and not indicated to the user in any way. Either add to the default command list, or add a helper message about shortcuts.

Hello @mvdicarlo, my name is Rafael and I am a student at the Federal Technological University of Paraná in Brazil. I am currently studying a subject in which I need to make some contributions to open source repositories. I wonder if you could give me some tasks so I can help?
