I use commandtab to browse through my applications, and command` for browsing through internal windows (e.g. for Firefox).
However, regularly, I switch to an application (e.g. TeXMaker and others) and only the menu bar shows up. They don't have a windows option, so I have to go all the way down to the Dock, find the application (which will have a dot on it) and click it. Then the windows will actually show.
I prefer not to use my mouse for this task. Is there any shortcut for this?
