I have a row of macro keys on my keyboard on the left side. I thought I’d be smart and add copy and paste macros (that were near mm’s away from Ctrl) and I never used them.
Muscle memory would always take over and I’d Ctrl+C Ctrl+V. I realized it would take more work to train myself to use the macro keys (and God forbid I used a different keyboard) than I was saving not having to press a key combination
For future reference, double space at the end of a line to start a new line, double enter to skip a line.
