Keypress event handlers shouldn't be anonymous

[dylanh724]

Hi,

Please properly identify the keypress event handlers (currently anonymous) so we can remove them if we want. Eg, an actual handler func called on keydown. Eg:

function pyDataCtrlKHandler(e) {
    // Original listener logic here
}
window.addEventListener("keydown", pyDataCtrlKHandler, true);

Real example use: We added Algolia DocSearch that replaced the search and uses the same hotkeys (eg, CTRL+K).

Cheers

good idea. Do you have time for a PR to implement this?
