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: cw.runAlgorithm(alg) # 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()) shortcut.setContext(Qt.ApplicationShortcut) shortcut.activated.connect(openAlgorithm)
That's it! If you press Ctrl + 1 the Join Attributes UI will open:
Note 1: You can get the names of the available algorithms by entering these lines in the QGIS Python console:
import processing processing.alglist()
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.
