I am afraid they haven't done a proper job (any job) of help for disabilities, such as providing comprehensive shortcuts for ease of use.
Unfortunately, given the speed and quality of ADE development, I am afraid they are unlikely to any time soon.
There are some things can be done. I am not saying they are good; but maybe not so bad ....
ctrl-T will toggle the sidebar.
The tab key will move over the various fields.
Tab as far as the Bookmarks header and hit space to see your bookmarks.
Tab some more to go through the bookmarks.
Hit F2 when on a bookmark to rename.
Also, if you have a fairly technical friend, they may be able to set you up some convenient shortcuts
using a program such as AutoHotKeys or Hotkey Master.
