In my head it does not exist. Never trust myself to remember anything, write everything down in a system you trust (TickTick for me). In the same vein when leaving tasks halfway I write myself what I had planned to do next and all the details I can quickly jot down, even if they seem obvious or like I won’t forget them.
I hit the windows key, type and hit enter to open programs a lot. I literally have no desktop icons showing, I don’t like the look and taking my hands off the keyboard to click stuff takes longer anyways.
I also do windows + number to open/switch to pinned programs a lot.
