What Are Chrome Flags?

I'm on the chromeos beta channel and often when I report something on the bugtracker there will be a comment like "Hey, can you try with flag #xyz disabled". It often works which is nice for me because it fixes the bug and nice for them to pinpoint the cause.
So I had to disable that flag until the bug got fixed and the fix deployed.
But there are more flags too that I have changed long-term:
#top-chrome-touch-ui - disabled
#focus-follows-cursor - enabled
#crostini-qt-ime-support - enabled
#crostini-virtual-keyboard-support - enabled
