Spell check keystroke popup

Hi, I use ctrl+enter to send email and I have spell check on send set (I like it). There may be a typo or word the dictionary doesn’t recognize, and I get the dialog. Many times I just want to send the email anyway without EMclient spell checking all my pasted code or technical writing, and I would love to just hit CTRL+ENTER again.

It seems that the Send button, lit at the top right doesn’t have a keystroke and can’t be triggered by keyboard without hitting the mouse. I do see there is a shortcut appearing to be defined for it but I can’t get it to work. Any ideas?
