You are right SullyJason but if you install magislr button (https://addons.mozilla.org/en-US/thunderbird/addon/902) you do not need CTR-Shift-Enter just click on the button sent it later.

Problem both addons are not Thunderbird 3.0 compatible.
Andrew C. Brown needs to work on it we need the must have BlunderDelay addon.
