Shortcuts -- how to add a new one?

Hi…

I am new to eM Client.  I don’t know what took me so long since this is by far and away the best email client I have ever use (and it’s been a lot of years).

I’m using v. 7.1.307940.  I plan to upgrade to the Pro version to support you.

QUESTIONS:

Is it possible to create a new shortcut?  I’d like to add one for use when composing an email using Alt+M+I+N?  That is for inserting a line within the email.  I have looked at Menu>Tools>Settings>General>Shortcuts, and I don’t see a way to add a new shortcut.  In the Send Mail section, I see how to change the shortcut key, but not how to make a new shortcut.  Of course, I can simply use ALT-M+I+N to insert a line, but I’d prefer to use just one key, like F2 for example.

In Menu>Tools>Settings>Appearance>Toolbars>Main Toolbar>Customize, I don’t see a way to add an item to the Available items list.  I would like to be able to add a toolbar button to bring up Rules and Settings without having to go through the Menu.  Perhaps that could be added to a “wish list.”

Thank you.
