When inline-renaming a file with a relatively long name, the name is shown in multiple lines. Pressing the Home/Pos1 key on the keyboard does not move the cursor to the beginning of the filename, but to the beginning of the "virtual" line the cursor is currently on. Reproducible: Always
I can reproduce this too. Dolphin version 15.08.2 (just like the reporter)
That is the normal behavior, existing in Dolphin since years. Please make a feature request if you want a different behavior, but this is unlikely to happen
