Code: [Select]
Identifier not found "key_Tab" error when I try to use the constant key_Tab, which exists in the documentation. I am new to Lazarus and Pascal.

You need to add lcltype to your uses clause. But this doesn't solve your particular problem, because the VK_ codes are virtual key codes, not characters. Virtual key codes are used in the OnKeyDown and OnKeyUp events. If you simply want the tab character, then use #9.
