Most tools have a UI button you can click to open then. A few can only be accesed by pressing a hotkey (example: custom script tools).

But there is not an in-game list of all vehicles that I'm aware of.

Thanks for your help. I misunderstood something I read that suggested there was a vehicle list in game.

I am aware of the tools with buttons & keybindings which are listed in the in game help. I wanted to make sure that I was not missing any that are not listed in keybindings.

There is a all vehicle list ingame but only a few uptodate paks have it:
pak128 german,
pak128 brit ex ...

Thanks. I can stop looking for one in Pak128. I refer to the online list often with the link you gave me the other day.
