Hey !
I don’t know if that’s already been suggested but would it be possible to add some setting to make the spacebar, and left arrow, start to edit the selected command ? That would edit the command only if no text has been entered to filter, else the behavior should not change from how it is now. For example, if I have my last command being ./a.sh , I’d like to be able to press arrow up to browse my last commands, and then just press space and edit it in my prompt (with an added space) to just add parameters before running it, without needing to press tab (and same for left arrow, to go back and edit an arg).
