I have a Logitech MX revolution and do the following - in the Logitech Software I set a 'keystroke assignment' for the button (lets say PgDn) and then use the code PgDn inside Party EzCASH - that should set off the key. You can also use a combo like Control and F by typing the keystoke as Control+F in Logitech and then ^F in Party EzCASH (^ is control).
Can you set a keystroke assignment that way with your Logitech?
You create the menu on the front tab of the GUI - double click an item to add/remove it to your menu (the items I have added in the picture are circled in blue below). Then set your hotkey (I have control h which is circled in red below).
Then hover over a Party table and press the hotkey when you want the menu to appear and press the button for which item you want to use.
Probably best to read through the
help here for best instructions.
