How to customize FoxitReader shortcut keys

Recently, FoxitReader for Linux was officially introduced and I love it.

http://www.webupd8.org/2015/09/foxit-pdf-reader-sees-new-linux-release.html

However, somehow FoxitReader does not support shortcut keys for any comment tools. This is quite inconvenience for me, especially when I have to use the trackpad of my laptop to select the tool first.

So I would like to ask if is there any way to configure the shortcut keys of FoxitReader?

I do not see this feature in the preference of FoxitReader, so looking into the configuration files of FoxitReader in Linux could be a possible solution. But I am don't know how to do it.

Thanks for taking time reading my post!

Not sure for linux but in window u can do this Right click on toolbar at top

Update:

Foxit version 2.4.1

By default, they provide for highlight light text using Ctrl+h (Linux)
