Changes

• Change 'ToggleExclusiveKeybd' to 'ToggleHotkeyMode'. Now you can use two independent hotkey schemes (mode=0 or 1).

  <config>
  <hotkeys>  <!--  The required key combination sequence can be generated on the Info page, accessible by clicking on the label in the lower right corner of the vtm desktop.  -->
    <tui key*>  <!-- TUI matrix layer key bindings. The mode=0 is implicitly used by default. -->
      <key="Ctrl-Alt"              action=ToggleHotkeyMode/> <!-- mode=0 binding for Toggle hotkey mode to mode=1 by pressing and releasing Ctrl-Alt. -->
      <key="Alt-Ctrl"              action=ToggleHotkeyMode/> <!-- mode=0 binding for Toggle hotkey mode to mode=1 by pressing and releasing Alt-Ctrl (reversed releasing). -->
      <key="Ctrl-Alt" mode=1       action=ToggleHotkeyMode/> <!-- mode=1 binding for Toggle hotkey mode to mode=0 (default) by pressing and releasing Ctrl-Alt. -->
      <key="Alt-Ctrl" mode=1       action=ToggleHotkeyMode/> <!-- mode=1 binding for Toggle hotkey mode to mode=0 (default) by pressing and releasing Alt-Ctrl (reversed releasing). -->
    </tui>
    <term key*>  <!-- key* here is to clear all previous bindings and start a new list. -->
      <key="Shift+Ctrl+PageUp"     action=TerminalViewportOnePageUp/>   <!-- mode=0 binding for Scroll one page up. -->
      <key="Shift+Ctrl+PageDown"   action=TerminalViewportOnePageDown/> <!-- mode=0 binding for Scroll one page down. -->
      <key="Ctrl+PageUp"   mode=1  action=TerminalViewportOnePageUp/>   <!-- mode=1 binding for Scroll one page up. -->
      <key="Ctrl+PageDown" mode=1  action=TerminalViewportOnePageDown/> <!-- mode=1 binding for Scroll one page down. -->
    </term>
  </hotkeys>
  </config>

• Rename DropIfRepeats to DropAutoRepeat.
