Not a real plugin, but I used a plugin to change startup
behaviour (here the styledtextctrl keybindings):

import wx

def Plugin(DrFrame):
[tab]->    DrFrame.txtDocument.CmdKeyClear(wx.stc.STC_KEY_DELETE, wx.stc.STC_SCMOD_CTRL)
    DrFrame.txtDocument.CmdKeyAssign(ord ('W'), wx.stc.STC_SCMOD_CTRL, wx.stc.STC_CMD_DELWORDRIGHT)
    DrFrame.txtDocument.CmdKeyAssign(ord('D'), wx.stc.STC_SCMOD_ALT, wx.stc.STC_CMD_LINEDELETE)
