Currently, as it stands, no matter what key you enter in calc, if there is an AutoInput suggestion, it accepts the suggestion. So, for instance, if I have I_DISLIKE_CORN_ON_TUE then the next time I start a subsequent cell and start typing I_DISLIKE_CORN then I have to hit backspace in order to not accept the AutoInput suggestion. I feel that this causes the user to have to, more often than not, hit backspace more times than what AutoInput saves in keystrokes. The user decides that turning it off is better than having it on. A better usage would be to have the ability to accept the AutoInput suggestion only when hitting shift+tab or whatever key combo the user would like in order to accept the suggestion. Alternatively have AutoInput only be confirmed using the arrow keys as this would still save time over typing the rest of an arbitrary number of characters.
Hello msounhein, in Calc menu “Tools” there is an option called “AutoInput”, you can turn it On or Off by clicking on the menuitem. You could also assign a shortcut key to the AutoInput menuitem, via Tools:Customize:Keyboard … then select Functions Category = “Options”, Function = “AutoInput” … then select your preferred shortcut Key in the listbox “Shortcut Keys”, then click the “Modify” button
