Wish IDE invert an equation

A hotkey to invert an equation would have been handy a couple of times

lets say you have:

this.a = get.z
this.n = get.l
that.f = put.x

and you want to have this quickly:
get.z = this.a
get.l = this.n
put.x = that.f

a hotkey to swap that in a election would be awesome.

long ago i thought about a assignment with direction
a => b copy a to b
a <= b copy b to a
or with a arrow
a -> b
a <- b
or as
a > b
a < b
or with an unicode char

or with a variable direction as parameter works at runtime
a d b
a d b
