Coming from many years as both an MS Office and Google Docs user, I have developed a habit of pressing [Tab] to complete the formula suggestion (i.e. autocomplete ‘=slo’ to ‘=SLOPE(’ by simply pressing [Tab]. Is there a way to chance Calcs autocomplete from [Enter] to [Tab]?
You can’t change Tab for Enter. This function is set choosing menu Tools - AutoImput.
By the way, if you type =SL and press Ctrl+Tab you could choose between =SLOPE and =SLN.
