How to scroll in insert mode?

Question

Is there a default key for scrolling in insert mode? I know that I could just

:imap <F5> <ESC><C-e>a
:imap <F6> <ESC><C-y>a

but I'm wondering if there's any key binding there by default.

For completeness, there are two dedicated commands for scrolling in insert mode, CTRLXCTRLE and CTRLXCTRLY. They are probably the proper ones to map.

See the documentation here: :h i_CTRL-X_CTRL-E.

In normal mode CTRLE and CTRLY do the same thing, I use them quite often.
