I am currently working on creating a reports in Power View on Sharepoint.
And here is a list of some keyboard short cuts I have found useful.
CTRL + M – Creates a new view (just as inserting a new slide in PowerPoint)
SHIFT + F9 – switches to Full Screen mode
TAB – Cycles through the different elements in the current view
SHIFT + F8 or CTRL + F8 – Will enable accelerator letters in the ribbon
ARROW UP/Down – Cycles through the different views
CTRL + F6 – Enters the Fields List
