Stuck in command mode for newbie

[amkmt]

I understand that when you type something in the cell, you will be automatically in edit mode (green border). Strangely, mine is never green; I am always in command mode (blue border) all the time. It doesn’t matter what I did; pressing Esc didn’t help. I’m on Mac.

You are likely not stuck in the mode; it’s just that the border colors don’t change in that manner now in modern JupyterLab and Jupyter Notebook 7+.

See here for basically the same question from almost exactly a year ago.
This part here probably summarizes it most succinctly:

@fomightez

The specific color indicators don’t work that way anymore.
The ways to change mode work much the same way as noted.

Click inside a cell to enter the editing mode. The active cell box will acquire a blue highlight around it.

Enter command mode by pressing Esc or using the mouse to click outside a cell’s editor area. The code cells will not have any blue lines around them and instead will all appear gray.

If ever in doubt about your experience, go here and click the ‘launch binder’ badge. You’ll get a fresh temporary session on a remote machine with one of the latest versions of JupyterLab. You can use that and eliminate browser extensions as a variable by trying different browsers where you maybe didn’t install any extensions yet.

Thank you, I thought I missed something.

I was scratching my head wondering why mine wouldn’t turn green either. It’s a bit of an adjustment if you’re used to the older versions, but knowing it’s just a UI change and not a bug is a huge relief.

I’m also using a mac, with Safari, and Jupyter Lab. I understand and can see the blue outline going on and off. But, when it is on, I still can not cut and paste lines of python from the cell window. At least, not by using mouse clicks. When I right-click (using logitech MX for Mac) the pop-up menu has “Copy. Cell” “Cut Cell” etc. Is there a way to cut and paste on the Mac/Safari using the mouse in Jupyter Edit Mode

That is a browser level action, so you’d use the options that come up under Safari’s ‘Edit’ menu up along the main menu toolbar ribbon at the top of your screen when Safari is open.
The Right-click in the cell shows you cell-specific context possibilities.

I just tried it when the blue outline is on in both a fairly up-to-date Mac Safari and an old one and it worked the same in both. If you aren’t seeing this be the case, is it possible a browser extension is enabled and interfering/intercepting? If that is not the case, then this issue should probably be brought up in a new thread. This thread has a title that addresses something very specific & should probably be kept clean to help those ending up here see the solution easily.
