If you find yourself clicking the same button in the Power BI Desktop you might find this little tip useful.
When you right click a button in the ribbon – you can add it to the Quick Access Toolbar.
This will add the button at the top (unless you have positioned it below the ribbon)
The button in the quick access toolbar can now be activated using a shortcut key combination.
When you press ALT the buttons will be labelled with numbers
So, pressing ALT + 7 will I my case open the Query Editor –
You can use the same technique in the Power Query Editor so by pressing ALT + 2 in my Query Editor will open the Advanced Editor
Hope this can help you too and do things even faster in Power BI with fewer clicks.
