Buffered curves now can only operate on themselves, matching by LongDisplayName. The operations are also restricted to the selected curves (either selected in the tree or selected by way of selected keys). There is a new option to Swap Buffered Curves which stores the current curve to the buffer and restores the buffer to the current curve. The Store/Swap/Apply menus are now visible for all the context menus (keys, hovered curve, all curves). There is also a new toggle to show/hide buffered curves and they are also only visible when the curve is selected. #jira UE-143895 #preflight 62294f800d5a90e98ed4ae68 #rb mike.zyracki #ROBOMERGE-AUTHOR: max.chen #ROBOMERGE-SOURCE: CL 19344793 via CL 19346614 via CL 19351363 via CL 19351424 #ROBOMERGE-BOT: UE5 (Release-Engine-Staging -> Main) (v926-19321884) [CL 19351984 by max chen in ue5-main branch]
