k key messing up while editing label track

When typing ‘k’ on label track, instead of showing the glyph ‘k’ it actually points the cursor to the end of the audio clip.

Which version of Audacity are you using?
Help > About, maybe?

It’s been a bug for a long time. See the workaround in the Release Notes .

Undo and redo basically.
