Often i need to close some other window and keep working in current window.
For example, if i read some help in upper window, and i edit code in lower
window. In the definite moment i decide to close help window. To do it,
i have to press "Ctrl_W k :q".

Not very short. And this is not the worse variant.
Other variant:

+-----------------+-----------------+
|      help           |                        |
|     window      |                        |
|                         |     current      |
+-----------------+     window     |
|                         |                        |
|                         | <cursor>       |
|                         |                        |
|                         |                        |
+-----------------+-----------------+

Focus is in the 'current window', cursor is on the <cursor> sign. 
I want to close 'help window' and keep working in current window.

That's what i need to do: 

Ctrl_W h Ctrl_W k :q Ctrl_W l

This is very long!
So, i wrote this plugin to make it easy.

It provides 5 commands.

Firstly, four commands for most-frequently actions:

      :Qh means "close left window and go back"
      :Qj means "close lower window and go back"
      :Qk means "close upper window and go back"
      :Ql means "close right window and go back"

And one universal command:
      :Q <args>, where <args> is movement commands to needed window.
      
      For example, ":Q hk" means "Go to the left window, then go to upper window,
                                  close it and go back to source window"

      So, this long long command "Ctrl_W h Ctrl_W k :q Ctrl_W l"
      is truncated to short expression: ":Q hk"

There's one optional dependency: CmdAlias plugin (vimscript #746).

If CmdAlias is installed, then lowercased aliases of commands will be available:   :qh, :qj, :qk, :ql, :q <args>.
I found it useful.


Please NOTE: 

1) if :Q without arguments is passed, then current window becomes closed.
   (to provide compatibility of lowercased command :q)

2) If argument is passed, but target window is the same as current window, then
   no window will be closed.
