A shortcut key for switching between Value and speed graph

Please add a dedicated, assignable keyboard shortcut to toggle between the Value Graph and the Speed Graph in the Timeline's Graph Editor.

Currently, this requires a right-click and menu navigation, which is slow and disrupts workflow. A single keystroke would dramatically speed up animation refinement for all users. This is a high-impact, low-effort feature that would significantly improve the daily efficiency of motion graphics artists and animators.
