Question

I want to use the following code to quickly go from insert mode -> command mode. The problem is it just doesnt seem to be registering my keys. I’ve tried with control (nothing happens) and i’ve also tried with command (D) and it just says spellcheck not activated.

" Quick command mode from insert
imap <C-;> <esc>:   

How do i go about doing this? is there an easier vim way that I’m not aware of?

Certain Ctrl chords can’t be mapped, including Ctrl-;.

This is mentioned in this FAQ, see also the Vim FAQ:

20.4. I am not able to create a mapping for the <xxx> key. What is wrong?

First make sure that the key is passed to Vim. In insert mode, press Ctrl–V
followed by the desired key. You should see the keycode corresponding to
the key. If you do see the keycode, then you can create a mapping for the
key using the following command:

:map <C-V><xxx> <your_command_to_be_mapped>

For more information, read

:help map-keys-fails
:help :map-special-keys
:help key-codes

The tip about trying to print the character using Ctrl-V is good to remember if you run into this problem with another key combo.
