In general I don't like pressing three keys at once, even if ctrl+alt = altgr, it is easier to use something like ctrl+?In this case I would like to use CTRL + MAnd in your picture it is show "open serial monitor" can be set to true/false, but this is only the action (upload OR upload+monitor) for the arrow next to "verify". I am refering to the keyboard shortcut.
The shortcut CTRL+I prints a tabulator in Notepad, too.And I prefer using CTRL+some key instead of pressing three keys and what about letting the user change the setting in the configuration file?
I still prefer Ctrl+M Ctrl and Y is very near each other (german keyboard, QWERTZ) so I would need to use the right ctrl-key. It is ok, though
Thank you very much looking forward to downloading the new version
