I'm looking for a way to uncheck the selected check box/radio button/toggle button using the keyboard in Windows 7, preferably in XP and Vista as well. I know you can use the Space bar to toggle the state of the currently selected button, but is there a way to set a control to ticked or unticked without risk of toggling it if is is already in the desired state?

If they are in the desired state, why would you want to tick/untick? – Terry Aug 13 '12 at 8:02
djerry certainly has a point. However, I don't believe there is a way to specifically "uncheck" (or "check") a checkbox/radio button regardless of its current state, unless the software provides this functionality (eg. a "select all" option perhaps) – w3dk Aug 13 '12 at 8:36
@djerry, I think what LodSfo is looking for is a way to ensure that the control is set to the desired state. Where spacebar always toggles, is there a way to initiate a "check" or "uncheck" command directly? I just submitted an edit to that effect to clarify it. – Nick Aug 16 '12 at 18:03

Use the Tab key or the mouse to select the check box and then press space bar key

This worked in Windows 7. – Napolean Jun 20 '15 at 7:32
Bonus: hold shift and press tab, you can select the previous check box. – RogUE Aug 13 '15 at 12:46
-1, has nothing to do with the question. LodSfo already nows pressing space, so he will now how to reach it. – relascope Mar 10 at 23:44

To check/uncheck a checkbox (tested in Windows 7):

+ to check
- to clear

Doesn't work for me on Google Chrome, version 43.0.2357.130 on Windows 7. – mabho Jul 12 '15 at 23:29

There is no way to control this for sure.

There are underlying controls that have default behaviors in Windows forms. Factors such as if these controls are a part of a control group will also have an affect on the outcome.

Also, there is no way to know how a developer handles certain events based on control selection and changes.
