Bind for mana amber?

I'm trying to make a bind to do a mana amber on my evie, but with only 1 button. I don't know what command to put. I tried

bind ctrl "+jump +jump" and it doesn't work... (figures...)

As for why I wanna do it, it's because sometimes when I'm doing a big raid like titan, if I want to amber myself, and there's lot of action like transformations or evies spamming magic, it doesn't seem to register the double tap. All I do is 2 hops, and I double tap my space bar pretty fast, so I don't think I'm too slow on my thumb I dunno if it happens to others too, but maybe it's because my pc is getting old lol

Anyone got a bind for that or is there a command that actually activates amber?
Thx!

I haven't tried this but might as well try
bind key "+jump;+jump"

You can try "+jump;-jump;+jump;" but if your client is lag-losing your keystrokes I'm not sure this will help. Hell I'm not sure it's even possible.
I do recall seeing a utility from someone in KR that intercepts a single keystroke and reinterprets it to Vindi as the mana amber sequence. I've never tried it though.
