So, I can't browse to the right side of the matrix_plot? documentation. https://ptpb.pw/2A4W.png

Another problem is unlike jupyter-notebook I can't delete one word at a time, forward or backward as Ctrl+backspace doesn't work, as it is reserved for moving text back to the previous cell.

I can't even reach the end of line and the start of line using alt+> as those too are not built-in?

My main problem is editing , and clearing one word using backspace+ctrl, is there an equivalent command?

edit retag flag offensive close merge delete

there is a reference entry for matrix_plot, if it helps! the link you posted sends me to a lot of strange symbols that i couldn't make sense of (i'm in Firefox).

@mforets right ,sorry typo. It is .png not .ng, see the edit above, and I can't clear one word at a time, using backspace, so yes, editing does become a problem.

jupyter was running exactly one time on my machine, and never again. (For similar reasons.) emacs + eclipse + sage interpreter in a linux shell is all i need. For the second problem, there may help:

At this point, sagenb is essentially unmaintained. The plan is that in sage 8.0, the jupyter notebook will be the default. I did notice that at least in firefox, the output of matrix_plot? does have a horizontal scroll bar at the bottom. Also, if you hit "TAB" rather than "SHIFT-ENTER" the help open in a slightly different way that does wrap (and can be popped out). Anyway, I wouldn't recommend investing much into learning how to operate sagenb at this point, but use Jupyter instead.
