I use AutoHotkey to make my own shortcut keys.
To start AutoHotKey at boot you need to put your autohot key in the folder “%appdata%\Microsoft\Windows\Start Menu\Programs\Startup”
My AutoHotKey config file:
;Shift + Arrow left - Mark line left of cursor position +Left::Send {SHIFTDOWN}+{HOME} ;Shift + Arrow right - Mark line right of cursor position +Right::Send {SHIFTDOWN}+{END} ;Ctrl + Arrow Left - Jump to start of line ^Left::Send {HOME} ;Ctrl + Arrow Right - Jump to end of line ^Right::Send {END}
