The grisbot program written in the Arduino IDE has grown to 20K, or about twenty typewritten pages. It takes many sessions to write the code and then to revise it. When I take a break and come back later, how do I find the place where I left off?

Well, instead of relying on aging memory or scrolling for wasted minutes, my very simple tip/trick is to foresee the problem and make a ‘bookmark’ comment can later be quickly located with the IDE’s Find feature:

Sadly, the Find has to be done on each tabbed section in the IDE code, but still this technique is a time saver.
