Hi Bohumil,
I've looked into the TrakEM2 source code, and:
F11 selects the pen tool;
F12 selects the brush tool.
See:
https://github.com/trakem2/TrakEM2/blob/master/src/main/java/ini/trakem2/utils/ProjectToolbar.java#L267If these aren't convenient, it's easy to create other ways to activate
the pen tool or the brush tool. For example, you could create a mouse
listener that recognizes a gesture, which could be e.g. moving back
and forth within a corner or a screen, or something similarly easy
such as moving your mouse to a corner of the screen. I.e., in jython:
```
from ini.trakem2.display import Display
from java.awt.event import MouseAdapter
class ToolToggle(MouseAdapter):
def __init__(self):
self.outside = True
def mouseMoved(self, event):
x, y = event.getXOnScreen(), event.getYOnScreen()
if x < 100 and y < 100: # top left corner
if self.outside: # only toggle if mouse was outside
self.outside = False # prevent toggling until mouse is moved
outside and back in
if ProjectToolbar.getToolId() == ProjectToolbar.PEN:
ProjectToolbar.setTool(ProjectToolbar.BRUSH)
else:
ProjectToolbar.setTool(ProjectToolbar.PEN)
else:
self.outside = True
front = Display.getFront()
front.getCanvas().addMouseListener(ToolToggle())
```
Run the script from the Script Editor after opening TrakEM2, and your
upper left corner will be a toggle between both tools. All you have to
do is move the mouse there.
Haven't tested the above script, hopefully errors if any are obvious.
Hope this helps.
Albert
