Is it possible to assign a keyboard shortcut to a (custom or not...) script of the Processing Toolbox in QGIS?

I have not found any information about it.


This is an example of how to open the Processing "Join attributes" algorithm by pressing Ctrl + 1 (you can copy and paste it into the QGIS Python console):

# Function to open the "Join attributes" algorithm's UI
# See http://gis.stackexchange.com/questions/156633/how-to-launch-processing-tool-user-interface-using-pyqgis
from processing.core.Processing import Processing
from processing.gui.CommanderWindow import CommanderWindow
cw = CommanderWindow(iface.mainWindow(), iface.mapCanvas())
def openAlgorithm():
    alg = Processing.getAlgorithm("qgis:joinattributestable")
    if alg is not None:

# Assign "Ctrl+1" to openAlgorithm()
from PyQt4.QtGui import QShortcut, QKeySequence
from PyQt4.QtCore import Qt
shortcut = QShortcut(QKeySequence(Qt.ControlModifier + Qt.Key_1), iface.mainWindow())

That's it! If you press Ctrl + 1 the Join Attributes UI will open:

enter image description here

Note 1: You can get the names of the available algorithms by entering these lines in the QGIS Python console:

import processing

Note 2: See Qt4 docs for a comprehensive list of keys.

Note 3: You can call shortcut.activated.disconnect(openAlgorithm) to finish the association between the shortcut and your algorithm's UI.

    Thanks Joseph, I find it also useful for myself. I hope it solves the question by @snaileater – Germán Carrillo Nov 3 '15 at 14:17
