I am looking for a desktop recording application like democreator, which can automatically create tool tips of the input key pressed in the video being recorded. For example, when I press Alt+Tab, it will create a tooltip like "Entered Alt+Tab" and so on.
The Question is: Is there something equivalent to that for Ubuntu? I don't want to use Windows software via Wine.
Update: One answerer mentions keymon. Thanks. But it was not what I was looking for. Keymon runs on the screen blocking some area, and I wanted a tooltip like feature to be displayed in the video only.
