According to credits vobsub has some hotkeys, but neither description provides via filter .
So, questions are:
1) Are they exist indeed? If so, i am interested in hotkeys for quick changing delay (like F1/F2 in mpc-hc), if no - add them.
2) Could devs add some description about basic options (for example hotkeys list in "About" tab or plain txt in zip with filter).
