Short description of error
In the Text Editor under View menu > Area it says that the keyboard shortcut is "Ctrl Spacebar" to Toggle Maximise Area. However this keyboard shortcut does not work in this Editor. By default this is set to Text Auto Complete in the default Blender 2.8 keymap. However even if this option is unselected in preferences the "Ctrl Spacebar" shortcut does not Toggle Maximise Area. If you use the mouse to click the option in the menu it does toggle maximise area but the shortcut won't work.
Exact steps for others to reproduce the error
Open a new session of Blender 2.8. Go to preferences and under keymap and key-bindings search for spacebar and untick the option for Text Auto Complete. Change one of the editor windows to a Text Editor. Create a new text data-block. Try the keyboard shortcut "Ctrl Spacebar" while mouse is over the Text Editor and it doesn't toggle maximise the area as stated in the menu.
