In my daily work I use a lot vim as my editor and the tiling window manager awesome. In my opinion both are great tools. What I don't like about awesome (and multiple other tiling window managers) are the unpleasant key-combinations like WIN+ANY OTHER KEY.
Is there any tiling window manager, which behaves like vim with its normal- and insert-mode? Where you can hit for example the windows-key to get in the window-manager-mode (like vims normal mode), do some window-arranging and -moving stuff and hit windows-key again or some other key to get back into "insert-mode" where every keystroke is catched by the active window?
If not, is it possible to let the win-key or any other modifier-key behave like Capslock? So that you keep in Win-mode until you hit the windows-key again?
To be clear: I do not mean a window manager which behaves like vims window management, but which haves two different modes, which you can reach with a simple keystroke. One mode in which every keystroke is a window-management-command and the other mode, which sends every keystroke to the current active window.
I already saw this question, but I think it was misunderstood and closed without any meaningful answer.
