Is there a way to cancel the keyboard shortcut for h1 only?

[userofit123]

My post titles are not part of the post content textarea, there is a dedicated input for them. The titles are the posts h1, so I only allowed h2 and h3 to be added through the buttons toolbar, but pressing ctrl+h allows people to add h1s.

Is there a way to cancel only the h1 from that shortcut, or to redefine that shortcut to set only h2 and h3 by reconfiguring it?

Use the shortcuts option/parameter to alter the keyboard shortcuts.

This will disable the Ctrl-H and the Shift-Ctrl-H shortcuts:

const easyMDE = new EasyMDE({
  shortcuts: {
    "toggleHeadingSmaller" : null  // unbind Ctrl-H
    "toggleHeadingBigger"  : null  // unbind Shift-Ctrl-H
  }
});
