NLA bracket ] selection does not select for tabbing into action editing (active vs. selected)
Open, Confirmed, MediumPublic

Description

Operating system: Debian 10
Graphics card: n/a

Broken: Local git build: 2.81, a571ff2c16c6, master 2019-08-09
Worked: unknown

NLA Editor: Select-all, ][ bracket selection, etc. will highlight strips, and those can be, for example, moved around. However, they must be manually mouse-clicked, for them to be actually selected for Tabbing into editing their actions/curves. If this is intended operation, I do not see an indicator to distinguish between what the strips are selected for. (See 'More info' below).

Exact steps for others to reproduce the error
Make multiple strips. Select with a, or [, ], etc. (just don't select with mouse). Tabbing into edit mode will not work except on manually-mouse-selected strips. Select any strips with mouse and those will be editable when tabbing in to edit them.

More info
From what I can tell there is a separate selection for manually (mouse) selected strips. I don't see an option to convert the selection into a tab-editable selection of strips (do we have that?), nor any visual indicator to differentiate the type of selection the strip belongs to.

This is probably an issue with selected vs active strips. Hitting tab fails, because there is no active strip, but it should still work on the selected strips.

Select-all (a) also doesn't select for tabbing into action editing. There should probably either be a way to do this, or possibly something in the RMB menu or Select menu for converting the selection to the tab'able strips.

It looks like it's an issue of selected tracks vs selects strips, rather than selected vs active. Clicking on a strip selects both the strip and the track, while Select Prev/Next, Select All, and Box Select only select the strips. Further, with Deselect on Nothing enabled (as it is by default) box-selecting automatically deselects the tracks. All together, this makes predicting the selection state of strips and tracks harder than it needs to be. Some keymap tweaks, and a better visual indicator for track selection states, would make these behaviors a lot more predictable, but I haven't had a chance test it out with more complex animations.

I submitted a patch that adds an option:
"Keyboard Selections Activates Tracks (needed for Tweak Mode)":

It doesn't support box select yet.
