The spacebar does not have a keyword for key binding.

It's common in some systems for the Alt+Space keys to be equivalent to clicking the icon on the left in the window's title bar; this happens in Windows and Openbox. Why would you want this on the keyboard? Sometimes the window might be poorly positioned (or larger than the screen) in such a way that reaching the top of the window to move it is impossible (this has become rare, but it used to happen in Windows, requiring the use of Alt+Space, arrow keys, and Enter; in Openbox it's almost the same, but there's the problem of not underlining the letter that combines with Alt, so we don't know how to do it). But I'm not here to ask for the Alt+Space binding to be added (since the user can edit the configuration themselves), but rather to have the option of having a keyword to bind the space. I tried <Key mask="A" key="Space">window</\Key> and noticed that it doesn't work when it's key="Space"; it works by replacing Space with another key. There's also the fact that it only works after clicking on the title bar.

Try lowercase "space" instead of "Space" (works for me)

Good observation. It worked! I noticed that a common click in the middle of the window, after alt+space opens the first option (which is usually called 'File'), however, it's satisfactory.

It looks like issue can be closed. OK?
