Material: Prevent ESC key from closing the menu

[YonatanKra]

Is there a way to prevent the ESC key to close the side nav menu?
I tried to listen on the document's keyup event, but to no avail.

Can you explain your use case? The ESC key is enabled for keyboard accessibility purposes.

Hi,
My use case is quite simple - once the menu is closed, there's no way to get it back (this is the design of my app). I can overcome this by closing the menu (as happens now) and adding some 2em width div in its stead. Clicking the placeholder div would reopen the menu. I was hoping to avoid this extra logic by just disabling the ESC key event...

Can you not use md-is-locked-open="true || <expression>" ?

I have same problem.
While I open mdDialog, than press Esc and modal closed as mdSidenav closed to! And this is really problem. How can I prevent this function of angular material??

/**
* Auto-close sideNav when the escape key is pressed.
* @param evt
*/
function onKeyDown(ev) {
var isEscape = (ev.keyCode === $mdConstant.KEY_CODE.ESCAPE);
return isEscape ? close(ev) : $q.when(true);
}

Thank you for answer!

I love angular material but this is very poorly handled.

md-is-locked-open="true || <expression>" is a bad solution as it doesn't work as expected (strange twitching and bad response). The only other solution i found is to cut out line 93 of angular-material.js, what seems like an awful solution.

under Services ($mdSidenav)
https://material.angularjs.org/1.1.3/api/service/$mdSidenav
there was a glimmer of hope that onClose handler exists, that turned out to be a document bug or something?

$mdSidenav(componentId).onClose(function(){});
method does not even exist:

overall i don't have an idea how to solve this without going into source.
Using finally is also not a solution as escape doesnt have a trigger.
