Is your feature request related to a problem? Please describe.

Describe the solution you'd like
It would be great to have hotkeys for sliding to right and left. It may save a lot of time.

Describe alternatives you've considered
Don't see good alternatives.

Check out these hotkeys: https://labelstud.io/guide/labeling.html#Time-series-specific-hotkeys and let me know if they work for you in the latest version of Label Studio!

Unfortunately, these shortcuts do not work in the latest Docker build (v1.4). Also, you might consider alternative hotkeys for decreasing/increasing the region size -- alt+left is the keyboard shortcut to Go Back in Chrome.

Hi, @NickShargan ! We really don't have such hotkeys, but we are working on a good new shortcut system, and this will be there. I'll let you know when this happens!
