Not sure how to translate "handle" to spanish.

Hi, i recently proof read the spanish page for arpeggios and glissando and found the term "handle" refering to the tool to customize lines difficult to translate accurately. The literal translation is "mango" or "manija" but its confusing in spanish at least, i found the term "gancho" to be the most convincing but im not 100% sure, in english it literally means "hook". I think it might be better to use a longer term to define it in spanish, something along the lines of "control point" or something like that.
Maybe someone in the development team knows a native spanish speaker and they can discuss which term works best, i used the term "gancho" in all the pages for consistency but it can be easily changed.
It might also be that because spanish has so many dialects it sounds weird to me but to a spanish person (from spain) or someone living in another country in latin america sounds right, im not sure really. I am argentinean, our spanish is pretty different from the "neutral" spanish.
