Forget it, Wiz, no problem.
Don't go for modes, go for moves!
Move the levers and the yoke yourself, sort out the modes of automation later
What modes? TOGA is a single button press. Even LNAV automatically engages. Press it and climb away, manually or with the A/P engaged. Or are you suggesting there's no need to press TOGA? TOGA needs to be pressed regardless and if you can't handle that then you may need to re-assess your choice of career. Sorry but that's how it is.
Some great advice being given out here.
