<C-^> not recognized in mappings

[maxdarling]

When running :nnoremap r <C-^> in IntelliJ, nothing happens.
But mapping other control-key sequences works just fine, e.g. :nnoremap r <C-d>
And pressing Ctrl+6 in normal mode in IntelliJ swaps to the alternate buffer, as expected.

So it seems like the mapping doesn't understand the character sequence <C-^>?

(I'm currently using the following workaround :nnoremap r :e #<CR>, so this isn't super pressing.)

Hi, we had some issues with <C-^>. Could you please try <C-S-6>?
