“Remap to page key” (forward remapped key to site)

[DePoli97]

Hi,
I’d like to suggest a small but potentially powerful feature: the ability to remap a Vimium key to another page key, i.e. a key event that is passed through to the underlying webpage unchanged.

Why this matters
Currently, Vimium intercepts keys before the page sees them. You can either:

• map a key to a Vimium command (e.g. f → LinkHints), or
• unmap it so the page can use it (e.g. f for fullscreen on YouTube).

But there’s no way to do something like:

map f LinkHints.activate
map g sendKey f   # forward “f” to the page

This would be incredibly useful for cases where:

• You want to keep f for Vimium LinkHints (it’s the most natural position, similar to how many Vim users work),
• but still access site-specific f behavior (like fullscreen on YouTube), by pressing another key (g in this example).

Proposed syntax
Something simple like:

map g sendKey f

or

map g passThrough(f)

which would cause Vimium to synthesize and dispatch a key event for f to the active page.

• It gives users full flexibility while keeping Vimium’s interception model intact.
• Many advanced users have this exact need (e.g. fullscreen, site-specific shortcuts, web apps).

P.S. If this is something you’d consider adding, I’d be glad to give the implementation a shot and open a PR. It looks like a relatively self-contained feature and I’d love to contribute.
