I plan to make the following changes to the Syntax colors section:* Change name to Text and syntax colors, as not all colors are code-syntax related.* Make it a subsection of the previous Editing and navigation section, which is about editor and shell windows, which are what get colored. Begin by stating that both window types get colored.* Greatly reduce excessive white space.  Put item and default color on one line, such as * Strings: green, and single space lines.* Add missing item: color pairs* Correct instruction on how to change defaults.

Current:3. Syntax colors The coloring is applied in a background “thread,” so you may occasionally see uncolorized text.  To change the color scheme, edit the [Colors] section in config.txt.  Python syntax colors:    Keywords     orange   Strings    green   Comments     red   Definitions     blue   Shell colors:    Console output     brown   stdout     blue   stderr     dark green   stdin     black

Possible alternative, with additions and corrections:--------------------3. Syntax colors The coloring is applied in a background “thread,” so you may occasionally see uncolorized text.  To change the color scheme, edit the [Colors] section in config.txt.  Python syntax colors:    Keywords: orange  Builtins: purple  Definitions: blue     Strings: green   Comments: red Shell colors:    Console output: brown  Console error: black on red   stdin: black        stdout: blue   stderr: redOther colors:  Cursor: black  Selected: black on gray  Found: white on black

The alternative above matches the format of help.txt, except that the latter has the colors lined up.  The excessive addition of whitespace here was an argument against replacing help.txt with help.html (#16893).  I consider the proposed condensation to be most of a fix of a regression.This sentence, "To change the color scheme, edit the [Colors] section in config.txt.", is strange in that it for help.txt, it was changed in 2002-12-11 to refer to the Highlights tab of the Configure dialog.  In any case, the color list was added before that tab, but not seems not necessary.  As a 'repeat', it is subject to obsolescence if not updated, which it has not been.  So I think we should either drop the section or drop the colors and replace with a better description of what is being replaced.2.4. Text and Syntax colors Text is both editor and shell windows get color coded. The coloring is applied in the background, so you may occasionally see uncolor text.  To change the color scheme, use the Configure IDLE dialog, Highlighting tab.Colors can be set for the follow types of text. Python syntax in both editor and shell: normal code, keywords, builtin class and function names, user-defined class and function names, strings, and comments.Shell output: console output, console error text, user output, and user error output and tracebacks.  Other text: cursor, selected text, and text found by search.  Debugger breakpoint lines in the editor are indicated by a dark yellow background (not configurable).----Note: I believe the marking of found text is OS dependent and know that it is the subject of discussion in other issues, so this part needs elaboration.

I'd suggest that there is no reason to include the list of what elements can be coloured, as it's there in the dialog for anyone who wants to muck with it. Just the first paragraph (two sentences) would be sufficient I think. Even dropping it from the document entirely wouldn't be a bad thing.

I decided to keep a further condensed subsection.  I think there is a bit of extra info, and we may need or want to say more after other changes, such as for#7949, and the addition of a dark theme. The reference manual documents our current promises.
