Directly code on Edge!

[GatesLover]

Convert Edge into a coding note, like Note Pad ++ or PyCharm! Figure out a shortcut like "Ctrl Code" in the search box to enter the coding note mode! And import as many language as we can, like in Zhihu writing, they have more than 100 languages and all the formula we have in Calculus, linear algebra, probability theory and mathematical statistics, Fourier transform, common functions, sequence, circuit design, chemical formula, etc

Use Visual Studio code for coding which is free

to take notes, use OneNote online:

you can take notes in Edge collections and Export them to OneNote, Excel, Word etc. too
