Sometimes its need to hide the toolbar for a clean window, a right-click on the toolbar could help, but after that when you recall the toolbar, it dosent appear in the original place. It woule be better with a hotkey, but i dont know how, I tried "Set Toolbar=toggle" (Like Set STATUSBAR=Toggle) but it dosnt work.
Try this: Toolbar NAME=Applications TOGGLE
Replace "Applications" with the name of your own toolbar
Use Toolbar NAME= TOGGLE POS=
If you want to change the position of your toolbars automatically, DefToolbar may be help you.
Edit: Use Toolbar NAME= TOGGLE STATE=.
