In early student feedback, we're noticing that some students find it annoying to re-run all their cells top-to-bottom every time they re-open a notebook.
Here's a tip to make it less annoying!
Instead of clicking "Run" or using Ctrl+Enter to run the cells, trying holding Shift and pressing Enter on your keyboard. In addition to running the cell, this will advance your cursor to the following cell. This also works on text (markdown) cells. So, you can quickly use Shift+Enter to run top-to-bottom through the notebook (regardless of text or code cells), without mouse scrolling.
Enjoy!
