Disable F1/F9 add-in: easily prevent the notorious Excel annoyances

Function keys in Excel are indispensable. But there is a big chance of missing the frequently used F2 or ESC buttons, and accidentally hitting F1 instead. Your computer starts slowly loading Excel Help, and the task pane takes forever to shut down.

Accidentally hitting the F9 key isn’t any less annoying. Excel starts to recalculate all worksheets in all open workbooks. Nearly every time it leads to frozen Excel, disrupted work and file recovery attempts. For some Excel professionals, the measure of last resort is physically removing the F1/F9 caps from the keyboard.

With XLTools Disable F1/F9 feature, you can save yourself the trouble:

  • Disable F1/F9 keys for all Excel spreadsheets in a second
  • Easily enable back when necessary
  • Other shortcuts remain operational
  • No need to write a VBA macro every time
