1) Another aproach would be to create an alias with a list of tools you use regularly, and have it shown as default when you open FARR.
(Options/History options, Blank search shows files from launch history, or as if the search string was...)
2) If you don't like farr showing results, or want to actually show history on launch,
- assign a short regex to the alias (something like ff or jj) so you can bring it up easily.
- You can assign a custom hotkey to FARR and have it be launched with that alias already called.
From there you can use alt+number shortcut to launch items directly
