Dear Albert,
thank you very much for your answer, the code works fine (you'll see it at
the bottom of this mail)!
unfortunately however while scrolling back and forth through the sections
it suddenly and randomly stop working; the System Log shows this message

if KeyEvent.VK_1 == keyCode:
NameError: global name 'KeyEvent' is not defined

Running again the script is ineffective, closing and re-opening the canvas
is the only way, but this is very annoying!

Thank you very much for your help, and for your work.

Federico


from java.awt.event import KeyEvent, KeyAdapter
from ini.trakem2.display import Display, Patch

class MyKeyListener(KeyAdapter):
  def keyPressed(self, event):
  keyCode = event.getKeyCode()
  if KeyEvent.VK_1 == keyCode:
for layer in Display.getFront().getLayerSet().getLayers():
patches = layer.getDisplayables(Patch)
for patch in patches:
if "NFL" in patch.title:
if patch.visible == True:
patch.visible = False
else:
patch.visible = True
elif KeyEvent.VK_2 == keyCode:
for layer in Display.getFront().getLayerSet().getLayers():
patches = layer.getDisplayables(Patch)
for patch in patches:
if "GFP" in patch.title:
if patch.visible == True:
patch.visible = False
else:
patch.visible = True

elif KeyEvent.VK_3 == keyCode:
for layer in Display.getFront().getLayerSet().getLayers():
patches = layer.getDisplayables(Patch)
for patch in patches:
if "Ki67" in patch.title:
if patch.visible == True:
patch.visible = False
else:
patch.visible = True

elif KeyEvent.VK_4 == keyCode:
for layer in Display.getFront().getLayerSet().getLayers():
patches = layer.getDisplayables(Patch)
for patch in patches:
if "DCX" in patch.title:
if patch.visible == True:

else:

Display.getFront().getCanvas().addKeyListener(MyKeyListener())
