MacOS menu keyboard shortcuts

Is it possible to add keyboard shortcuts for menu items in the MacOS version of MEGAN?

For instance, when I use MEGAN on a Linux machine, I can export all the taxonomic classifications highlighted in the view window by hitting the alt key, f, t, t, which brings up a prompt window to save the output to either a csv file or tsv file. The macOS version does not seem to have the full complement of keyboard shortcuts assigned. Some are, some are not. Is it possible for me to edit the keyboard shortcuts somehow?

Thank you.

The problem is that ALT-key combinations are semi-automatically created for linux (and possibly windows?) but not for MacOS.

Thank you for making the time to respond. And thank you for all of your effort!
