Settings - Customize Toolbars
cilck [commands] ,then add this js code to user-defined command
function OnClick(clickData)
{
var v = new ActiveXObject("WScript.Shell");
v.SendKeys(clickData.func.args.KEYS);
}
Template：
KEYS/R[{TAB},{ENTER},{ESC},{CAPSLOCK},{NUMLOCK},{SCROLLLOCK},{BREAK},{UP},{DOWN},{LEFT},{RIGHT},{PGUP},{PGDN},{PRTSC},{INSERT},{HOME},{END},{DELETE},{BACKSPACE},{F5},{+},{^},{HELP},+,^,%]
Now，we have a new command "SendKeys"
create a button，use the code below：
@if:Set CHECKBOXMODE=on
SendKeys "^% "
@if:else
Select NEXT=nodeselect
for example，shortcut key：Insert
