While learning the matplotlib library, I learned about the 'shift+tab' combination. I was looking there and writing my codes. Today I opened Jupyter Notebook again, but the 'shift+tab' combination does not work. How can I access documentation on Jupyter?
"shift+tab", right click
If "Shift+Tab" is not working for you, there could be a few reasons for this. Try restarting the kernel by clicking the "Kernel" menu and selecting "Restart."
