I was wondering how to send a space key using SendKeys.send (); it works with other keys, but onley has a space!here is the link where i found other keys http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx
The documentation you linked will SendKeys.send(" ");send a space.
SendKeys.send(" ");
The only keys that require special codes are "characters that do not appear when you press a key."
Use application.sendkeys "{SPACE}"
