reminded about the help file for Gimp 2.10 in pdf format.
I checked if my version was current - it was older (Yune 25, 2019).
The latest version comes from November 11, 2019.
Thank you Rich for reminding me to check for updates.

I will remind you - a simple plugin on how to call this file from the Gimp menu: Help -> Gimp-help-2.10-en.pdf ...

Gimp-help-2.10-en.pdf (also for Windows):
http://gimp.linux.it/www/meta/

I use as a browser pdf - Free Foxit Reader (but it can be completely different).

Thanks Mareroq, helpful little plug-in
Edited the program and file path on Linux to use Okular automatically when launched.

A really small plugin - but easily modifiable to open various "items" from the Gimp menu.

@Nidhogg.
Please don't brag - just please - include the Linux version.

I didn't want to attach it because people use atril or evince usually on Linux. Just need to edit lines 28 and 29.
(PF_FILE, "program", "Program to open pdf:", "/usr/bin/okular"),
(PF_FILE, "file", "File to open:", "/home/"yourname"/Documents/gimp-help-2.10-en.pdf"), #if it's in your Documents folder

Thanks for the information.
