Please can someone tell me what may be preventing both of the Insert keys from working on my keyboard. Because neither of them work I have had to set up a keyboard shortcut by accessing:- Tools; Customise; Keyboard; Categories; All Commmands then scroll down to "Overtype"! Though this option shows "Insert" as being the key to activate the feature, it does not work so I have allocated [Ctrl + Shift + I] (which was unassigned to any other shortcut) & that activates the function.
