Neomutt binding questions for unread emails and sidebar navigation

Question

I'm working on setting up neomutt for the first time and have hit a couple of stumbling blocks with key bindings, and wanted to confirm if I was doing something wrong or if what I'm looking to do isn't possible.

Sidebar navigation

I've currently navigate emails using the up and down arrow keys, and the sidebar using the below commands I'd like to make things a little easier in my neomutt config, and change my sidebar navigation keys to be ctrl+Up and ctrl+Down. I've tried to use \C<Up>, \C<\Up\> and other variations but none seem to work.:

bind index,pager \Cp sidebar-prev       # Ctrl-p - Previous Mailbox

bind index,pager \Cl sidebar-next       # Ctrl-l - Next Mailbox

bind index,pager \Co sidebar-open       # Ctrl-o - Open Highlighted Mailbox

I'd like to make things a little easier in my neomutt config, and change my sidebar navigation keys to be ctrl+Up and ctrl+Down. I've tried to use \C<Up>, \C<\Up\> and other variations but none seem to work.

Does anyone know if this is possible/ how I should write the syntax, or is this not possible?

Email Flagging: Unread

Whenever I get a new email in, it is flagged with an O to indicate the email is currently unread. I'm trying to find out how I can mark an email unread even after I've read it (as I intend to use the 'toggle-read` option to filter out what I still need to action. I've had a look through the neomutt site for key terms like flagging but I can't seem to find the correct thing I'm looking for. That or perhaps I misunderstood the wording on the page.

Does anyone know if there is a keybinding to do this or if they can share which page on this site covers what I am looking to do, so I can review it?

Appreciate any help that can be offered here.

Managed to the answer to the first question via a bug post - https://bugs.freebsd.org/bugzilla//show_bug.cgi?id=213212

I found the below commands to work for me:

bind index,pager <C-Up> sidebar-prev            # Ctrl-Up Arrow - Previous Mailbox
bind index,pager <C-Down> sidebar-next          # Ctrl-Down Arrow - Next Mailbox
bind index,pager <C-Right> sidebar-open         # Ctrl-Right Arrow - Open Highlighted Mailbox

One can also use <S-Up> should they want to use Shift+Up for navigation. It seems <C-S-Up> isn't a thing that works for Ctrl+Shift+Up, but I'll update the post if I figure that out.
