For exmaple typing "Every": Now pressing Shift + Left will select "filled text" MINUS "last letter in filled text": However, a more intuitive behavior would be "filled text" PLUS "last typed letter" (like msedge does):
Which means the caret should be placed at the beginning of the autocompleted text. I checked the advanced settings and didnt found an option. It would be useful if you can add this. Thanks.
