CoolTerm ^Z^Z = Send?

On CoolTerm noticed that two quick Ctrl-Z can cause it to do a "send".
It pops up a progress bar, and seems to send back out recently received data, possibly some kind of Loopback test?

Same on CoolTerm V146 and V147, using Win10.
Ctrl-Z is grayed out on edit menu, so I'm not sure what ^Z^Z is actually intended to do.

Bug or feature?

This might be a Windows bug. When CTRL+Z is grayed out because there is nothing to undo, the text box control CoolTerm uses to display text shouldn't do anything. I wonder if instead it captures the CTRL+Z character, which is ASCII code 0x1A. CoolTerm for Windows actually has a preference setting that can disable all menu short cuts do that the CTRL key can be used to send special characters. More on what special characters are possible can be found in this thread:
However, with menu shortcuts disabled, keys pressed together with CTRL shouldn't get captured by the text field. I'll look into that. I'm currently traveling so it might take a few days.
