Description mau 2022-01-18 13:34:29 UTC

When adding clips to the timeline for the first time with a new project, I do the following:
- select first clip in project bin
- use keyboard only: use j,k,l-keys to play and i,o-keys for in- and outpoints and v-key to insert it into the timeline
- use arrow down to select next clip in project bin

Problem: the project bin doesn't follow the selected clip, i.e. it doesn't "scroll", so after a few clips the selected clip isn't shown anymore. I have to use the mouse to scroll down in the project bin, so I'm forced to switch between keyboard and mouse.

Solution: scroll in project bin such that there's at least always one or two clips shown to both sides of the selected clip, i.e. up and down.

Thanks for your report!

I can not reproduce your problem, for me the view follows the active item when I change it with the keyboard. Can you please fill out the reports meta data such as "Version" and "Platform"? These are very important information for each bug report or feature request.

I'm using an Appimage of 21.12.1 under Linux.

Well, the behaviour isn't new for me, I experienced it for several years but never reported it.

Following your reply, I just tried it again and have to state more precisely:
I open a project with several folders in the project bin and many clips under at least on of them. I select one clip with the mouse, than I use Arrow Down to select the next clip. As long as this clip is currently shown in the project window sub window, I see it selected (blue background). Now when the last visible clip is selected and I continue to select the next one by pressing Arrow Down, the highlighted "line" disappears, i.e. a clip is selected which is below the lower sub window border. If I continue pressing Arrow Down, the next clip is also "hidden" (second clip), but if I continue again to select the third clip, the view is updated, i.e. it scrolls down.

Since I usually just continue to the next clip and use my mouse to scroll when the highlighted line drops out of the project bin window, I never found out that is "self corrects" itself after a few more clips.

If I select clips up instead of down, the problem doesn't exist, i.e. it scrolls just fine. If I go down again, the same pattern does apply: 1st and 2nd clip are "hidden", for the 3rd clip the view is updated correctly.
