How to deploy application from tray from console?

Question

linux

Installed Linux mint 18.2 Cinnamon
I want KeePassX minimized to tray to unfold when hotkeys are pressed.
Here's a team that can do it

Answer 1

EMNIP cinnamon can call applications by hotkeys. And since the application is hanging in the tray, then calling it again will most likely open the tray and not launch a new application.

Answer 2

And if you find the pid of the program, then send a signal to the process to turn around?
