...and shooting...
3e Shot on the Run Feat (which has several preqs) and high DC Accrobatics. 4e Evasive Strike Ranger encounter exploit + Elf's Wild Step Trait.
5e "DM, may I surf down the stone staircase on a shield while shooting an orc with my bow?"
Stabbing with the arrow, then firing it?

5e Improvised weapon attack with an arrow, likely to miss, or do insufficient damage, followed by either another one, or taking the shot with the first orc still alive, with Disadvantage for the adjacent enemy. Also, even if you kill the first orc, it gets a dying attack against you.
Impaling two enemies with one shot?
3e. Penetrating Shot feat. 4e: Split the Tree, Ranger daily exploit
5e Piercing Arrow, Arcane Archer short-rest-recharge class feature that shoots an ethereal arrow through cover.
Climbing and shooting a moving foe?
3e Multiple high-DC Climb and acrobatics checks, shot technically provokes from the monsters. 4e Close Quarters, Rogue daily utility (Legolas, you naughty MC-feat taking boy) + Close Quarters Shot, Ranger encounter
5e "DM, may I climb up the monster while shooting the orcs riding it with my bow?"
...and killing it in one shot, mind you.
TSR-3e: I never thought I'd get to use this Arrow of Elephant Slaying 4e:
who knew it was a minion? (Gimli did,"it only counts as one!"
)
5e: +6d10 for an arrow of elephant slaying'll do it, right?
Being an elf who is sufferable?
What? Oh, not insufferable.
Not possible in any system. 4e: "But Tony, its the Eladrin who are insufferable." Eladrin are just High Elves, 4e, you're not fooling anyone.
TBF, the above is humorous, but it's interesting how 1e sneaked a bunch of stuff from LotR, like the spells Gandalf cast and his Staff pre- & post Balrog (type VI demon), and glowing magic swords and the Crystal Hypnosis Ball ('palantir' sounded a lot cooler), while 4e snuck Legolas stunts from the LotR movies into the Ranger - like, transparently. "Stab & Shoot?" c'mon....
