Calc Embedded Mode keybindings

Question

I am trying to use calc to modify equations in an org mode buffer. Activating calc in embedded mode works, but not without opening the calc stack buffer itself. That is, C-x * e puts the CalcEmbed mode line on my org buffer, and makes the buffer unmodifiable. However, the major mode remains Org. I have to run C-x * c to open the calc stack buffer, from where I can edit the equation, and have the changes automatically reflected in my org buffer.

Based on my reading of the manual, it seems like no stack buffer should be required. To whit:

When Embedded mode begins, Calc pushes the current formula onto the stack. No Calc stack window is created; however, Calc copies the top-of-stack position into the original buffer at all times. You can create a Calc window by hand with C-x * o if you find you need to see the entire stack.

Am I misunderstanding? I should note that I'm using evil, so keys like a and f are shadowed by the evil bindings. If I'm not misunderstanding, how can I more or less "turn off" evil mode for the duration of the Embedded Mode session?

Answer 1

Running emacs -q to bring up a clean session, then testing out the Embedded mode in a clean file, verifies that the embedding does indeed work without the stack buffer. Running C-z to temporarily disable evil is good enough for my use case.
