[Gimp-user] Can the Color Picker shortcut in brush mode ("ctrl") be changed?

[Jehan Pagès <jehan marmottard gmail com>]

Hi,

when in brush mode, clicking "ctrl" switchs to color picker until you
release. Is this shortcut editable? What if I want this to be set on
Alt instead, for instance?
I could not find any shortcut which looks like it would do this in the
keyboard shortcuts list. Is there one? How to change this shortcut?
Thanks.
