/bind ADD "target_custom_next base Myst"
Get way up high, turn slowly, keep whacking the keypad + key. It targets objects with the name "Mysterious Gift" at far beyond alt vision range. Hit your go-to button, especially if you're a flyer. Oh, look, it's for YOU!
(I find the Add button convenient; if you want to mouse-turn and whack at the same time... wait, that's not quite what I mean and leave Swan alone, you perv... if you want to turn-and-search, the tilde key (~) might be a better choice.
/bind ~ "target_custom_next base Myst"
(Caveat: I haven't logged in yet this year; I seem to recall the object name changing from time to time. Adjust those four or five string letters appropriately.) Confirmed.
Unfortunately, the /interact command ("click on what's in front of me") doesn't work with presents.
