gesture for selecting whole line in script editor

[Bushmills]

Currently, long push selects a word, same gesture again on an already selected word deselects again.
As deselecting is possible by tapping elsewhere, this gesture could be used to select a whole line, which is currently - to my knowledge - only possible by dragging at least one, sometimes both markers, which can be tedious. Given that selection of a whole line is done frequently (for swapping lines, or moving a line somewhere else to), having such a gesture should make those operations much more comfortable.
