I like this nice feature on texmaker
Options->Define Current document as 'Master Document' and find myself using it heavily since I have my bibliography on a different file.
It would be great to switch using a keyboard shortcut. Is there any way to make it happen? 'Coz it's not shown under current shortcuts list.
EDIT: well currently you can do this by using
CTRL + SHIFT + F2 but it's very inconvenient using this combo
