Hi, I've seen there is a contextual menu when right-clicking on the top of the timeline (where frame numbers are); but we need to be able to assign a shortcut for "insert 1 frame" and "remove 1 frame"; it's a must-have when timing animations. Also; maybe there could be two different functions : "layer > insert 1 frame" & "layer > remove 1 frame" "timeline > insert 1 frame" & "timeline> remove 1 frame" This could be great for the workflow (it's a pain to always select all layers) Thanks !
I confirm this would be a good thing to add, at least some shortcuts for the actions in the contextual menu of the timeline header. The other part about adding similar actions for all layers is another step that could be discussed.
I filled a bug for the layer commands : https://bugs.kde.org/show_bug.cgi?id=376886
Menu entries and shortcuts for layer insert frame and timeline insert have been implemented. The first as "Insert Column left/right" and the later as "Insert Keyframe Left/Right". I guess we forgot to close this bug.
