Unhide columns

Unhide any hidden columns that intersect the current selection.

Notes:

(1) May not work in Excel 2010 on Vista or Windows 7. Discussion and fix is here: http://superuser.com/questions/183197/whats-the-keyboard-shortcut-to-unh...

(2) May not work in Excel 2007. See http://www.techrepublic.com/blog/microsoft-office/office-solution-keyboa...

(3) In Windows 10, there is a conflict with a keyboard switching shortcut. You can resolve by un-assigning the keyboard layout hot key. You may need to un-assign the input language as well.

This is a tricky setting to find. You are looking for Advanced Keyboard Settings, under Region and Language.
