macOS keyboard shortcuts on Guacamole

[tavareshugo]

This is a problem affecting macOS users only, where keyboard shortcuts don't work properly on Guacamole.
This issue is an attempt to document some of the problems we encounter and how to solve them:

Language	Symbol	Shortcut
UK	#	right option + shift + 3 (the left option does not work)
US (I think)	#	Fn + Cmd + 3
Spanish	|	option + command + 1
