For me, I would reduce the functionality to just one key: ESC. I always pressed ESC key mindlessly when thinking of the next thing to write. I pressed too many useless ESC like fidgeting. If I can offload it to the foot...
I highly recommend this book. The chapters were "bite sized". Compared with the dinosaur book, it was easier to finish one chapter after I started on it. The chapters on concurrency made me cry with "so this is how XXX works" a lot. I also found the references near the end of each chapter were full of gems.
I self-taught CS, so not surprisingly there were lots of "void" and "dots" in my knowledge space. This book connected lots of dots together.
