Motivation

Small UX change to pass Shift+Home key combination to search input (Home without Shift is handled as usual), to allow selecting entered text. Delete key is passed to search input if search input contains any selected text. This allows to delete previously typed text without the need to hold Backspace. This change makes the text box behaviour more canonical. No other changes, previous key binds work as usual.
