Yeah, on Windows I created a floating palette using AutoHotKey to automate my frequently used commands (FUCs). 
However, in the end I realized that I am one of @Silverdragon’s YMKS people — self-knowledge is important, and this became a learning experience for me — so eventually I migrated this palette to be invoked via one shortcut, which gives me instant access to all of my FUCs.
Best,
Jim
