Command search is a really nice add-on to the interface, but it should be possible to go through the list of suggested commands using cursor keys and launch the command with hitting ENTER key. Right now we can type desired text and get search results, but to actually do anything with them one needs to use mouse and click appropriate command on the list.
It would be much faster to not take hands away from the keyboard and just go through the list with cursor keys and then run selected command with ENTER key.
