Shortcuts to hide/show panels in QGIS

Just a quick one to show how to assign shortcuts to hide and show for panels in QGIS. Add this to your .qgis2\python\startup.py

from functools import partial
from qgis.utils import iface

from PyQt4.QtCore import *
from PyQt4.QtGui import *

mappings = {"Layers": Qt.ALT + Qt.Key_1,
            "Browser": Qt.ALT + Qt.Key_2,
            "PythonConsole": Qt.ALT + Qt.Key_3}
shortcuts = []

def activated(dock):
    dock = iface.mainWindow().findChild(QDockWidget, dock)
    visible = dock.isVisible()
    dock.setVisible(not visible)

def bind():
    for dock, keys in mappings.iteritems():
        short = QShortcut(QKeySequence(keys), iface.mainWindow())
        short.setContext(Qt.ApplicationShortcut)
        short.activated.connect(partial(activated, dock))
        shortcuts.append(short)

bind()

and now you can hide and show using ALT + number
