Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Big Picture
The Selected Keyframes Panel would provide animators with a much faster keyframe editing capability in the Graph Editor: being able to Box Select keyframes and edit their values simultaneously.
Use cases
Design
UX
When multiple keyframes are selected, the UI shows the values of the first keyframe from the Box Selection. This is the first keyframe of the first F-Curve in the Graph Editor. In the original prototype, when multiple keyframes were selected and the values did not match, the value's label included an asterisk (*) decoration to show the user that they would be editing multiple keyframe values. @dr.sybren requested that another method is explored as it should be implemented in a wider scope than the Graph Editor. User Interface feedback requested. In an animation module meeting @JonMatthis proposed a light blue field decoration. Here is a mockup of this as colorized text fields aren't currently possible in Python Add-Ons (except the strong red for alerts).

I get the problem of box selection not setting an active keyframe (that is a "problem" throughout blender and is also discussed in #82359 (Stronger binding of Active and Selected))
Thx for the presentation, a couple of notes:
From testing here the {key Alt} tweaking behavior still seems to work for all this (frame, value on keyframes as well as handles), is this not working for you?
(See
Alt
in https://docs.blender.org/manual/en/dev/interface/keymap/introduction.html#properties)This is the current / usual method in blender for editing properties of multiple items selected, making this more obvious and improving upon this is also discussed in #54862 (Multi-Object Properties Editing) (including UI mockups)
Will check on this (maybe we should create a separate, isolated report for this)
Here is a patch allowing snapping of handles, too D13606: [WIP/eperimental] Graph Editor: support snapping handles
What I want to say with this is that as long as you make sure you have an active keyframe (and yes, box-selecting exposes the "problem" of active vs. selected), the whole concept of adding a new panel seem redundant?
@lichtwerk , you've made some great points and found some excellent related tasks. Thank you for taking the time!
I am aware of the {key Alt} tweaking behavior. Thank you for directing me to #54862 (Multi-Object Properties Editing) as this is something, like the author/supporters of this task, I'd very much like to see change in Blender. As you mentioned, not being able to do this with a Box Select makes the selection process extremely tedious.
Yes!! Thank you very much.
You are so right about these panels being redundant and it is because of redundancy/loose-binding of "Active" and "Selected." Solving #82359 (Stronger binding of Active and Selected) and #54862 (Multi-Object Properties Editing) would eliminate the need for this panel. I'm a little discouraged by that though because both are design tasks from 1+ years ago (2020 and 2018, respectively) still in discourse that have not been moved into implementation. I'm not sure how these things are typically decided in Blender, but I feel more confident in animators getting a better UX sooner with this panel than waiting for the dependencies. I will add my thoughts to those tasks and try to understand the status before moving forward.
I just checked in on the design of https://developer.blender.org/T54862 and it isn't progressing.
