Shortcut to exit scale mode in VirtualBox

What is the shortcut to exit scale mode in Oracle VirtualBox, Windows 7 host?

To exit Scale Mode, press:

Right Ctrl (Host Key) + c

---

Note that your (Host Key) may be different from Right Ctrl. To check the current binding, go to VirtualBox Preferences > Input > Virtual Machine > Host Key Combination.

If Right Ctrl (Host Key) + C does not work (there have been some issues on Ubuntu), do the following:

1. File > Preferences > Input on the Virtual Machine which is stuck in Scale Mode

2. Change or Reset the Host Key. There's no need to even save after changing the settings

3. Re-open the Virtual Machine and it should be reset!

Steps:

• host + f, to switch to full screen mode, if not yet,
• host + c, to switch to/out of scaled mode,
• host + f, to switch back normal size, if need,

Tip:

• host key, default to right ctrl, the control button on right part of your keyboard,
• host + c seems only work in fullscreen mode,

Yeah it suck to get stuck in Scale View.

Host+Home will popup the Virtual machine settings. (by default Host is Right Control)

From there you can change the view settings, as the Menu bar is hidden in Scale View.

Had the same issue, especially when you checked the box not to show the 'Switch to Scale view' dialog.

This you can do while the VM is running.

I arrived at this page looking to turn off scale mode for good, so I figured I would share what I found:

VBoxManage setextradata global GUI/Input/MachineShortcuts "ScaleMode=None"

Running this in my host's terminal worked like a charm for me.

I was having the similar issue when using VirtualBox on Ubuntu 12.04LTS. Now if anyone is using or has ever used Ubuntu, you might be aware that how things are hard sometimes when using shortcut keys in Ubuntu. For me, when i was trying to revert back the Host key, it was just not happening and the shortcut keys won't just work. I even tried the command line option to revert back the scale mode and it won't work either. Finally i found the following when all the other options fails:

Fix the Scale Mode Issue in Oracle VirtualBox in Ubuntu using the following steps:

1. Close all virtual machines and VirtualBox windows.

2. Find your machine config files (i.e. /home/<username>/VirtualBox VMs/ANKSVM) where ANKSVM is your VM Name and edit and change the following in ANKSVM.vbox and ANKSVM.vbox-prev files:

3. Edit the line: <ExtraDataItem name="GUI/Scale" value="on"/> to <ExtraDataItem name="GUI/Scale" value="off"/>

4. Restart VirtualBox

You are done.

This works every time specially when all other options fails like how it happened for me.

In MacOS Cmd+C is useful to minimizing the full screen

Another solution (poor one do) is exiting VM Box with saving desktop (top option), restart would bring back the screen as it was before the rescale.

as @MikeMiller pointed out, To exit scale mode: Right Ctrl (Host Key) + C
but for users who DON'T have a Right Ctrl (Host Key)
(such as MS Surface Pro users: we only have a Left Ctrl key), u need to go into Virtualbox>>File>>Preferences>>Input>>VirtualMachine tab>>change Host key Combination to one that works for ya(I used Ctrl+Shift+Alt which doesn't seem to be in use already)
