Few productivity questions about pattern editor and hotkeys

I could not figure these out myself so here goes:

Can you select individual track sections (volume, delay, effect column) for the whole duration of a single pattern with a hotkey? There’s a way to cycle selections for these parts, but the selection keeps extending only to 1/2 of the pattern’s length (or to whatever the pattern looper is set to, but it cannot be set to 1/1 as far as I know).

Is there a way to insert effect (or anything for that matter) for the rest of the pattern under active cursor. So let’s say I want to fade a string with Oxy effect. Usually I want this effect to reach to the end of the pattern with value O00. It would be nice if I could quickly insert O00 all the way to the end of the pattern with a single command. I hope that makes sense.
