Bug report

Bug summary

Pressing a key in a MPL plot causes a beep. This is not a serious problem, but is annoying.

Code for reproduction

use the code herehttps://matplotlib.org/stable/gallery/event_handling/keypress_demo.html, but add

importmatplotlibmatplotlib.use('wxAgg')

Actual outcome

Every time a key is pressed, I hear a bell sound (a beep).

Expected outcome

I should be able to eliminate this using this in the callback:

defon_press(event):event.guiEvent.Skip(False)    ...

The reason for this is in this callback handler inbackend_wx.py

def_onKeyDown(self,event):"""Capture key press."""key=self._get_key(event)FigureCanvasBase.key_press_event(self,key,guiEvent=event)ifself:event.Skip()

Since the method ends withevent.Skip() (same asevent.Skip(True)) the call toevent.guiEvent.Skip(False) is ignored.
If this is rewritten as:

def_onKeyDown(self,event):"""Capture key press."""ifself:event.Skip()key=self._get_key(event)FigureCanvasBase.key_press_event(self,key,guiEvent=event)

Then existing code will function as before, but there is the option to suppress the beep. One could argue that.Skip(False) should be the default, but that would be a change in how MPL functions.
