I'm brand new to speedrunning, and I've got 2 questions regarding livesplit.

1. I've just finished my first run, but I assumed at the time I had to start the timer from when I started moving rather than when I got the first speed boost. Is it still possible to upload the run and what should I do about the time?

2. What keybinds should I use for livesplit? I'm currently using Q to progress the timer but whenever I try to use splits for each level I mess up the start because I'm trying to press to many buttons.
