Can I turn off highlighting of TODO keywords? - emacs

I am using several normal verbs as TODO keywords. For example, 'Fix' is a TODO keyword, and when it gets done it turns into 'Fixed'. This works well except I find the highlighting distracting. Can I turn it off? Ideally I would like a task to be a simple sentence "Fix ..." with no special highlighting, but recognised as a todo item.
TODO keywords have the org-todo face by default, but changing this face doesn't do the trick. It reinstates the default if I turn off one of the attributes, and in any case the foreground should match the current level, so there is no one colour that would work. If It's org-level-x I want it to look like org-level-x.

Getting reftex recomendations for labels when creating new sections

In TeX-latex-mode under Emacs (26.1) using the reftex minor mode,
When pressing C-c (, the command reftex-label (found in reftex-mode-map, from reftex-ref.el) gives pretty good suggestions of label according to context for sections (with the default value of reftex-insert-label-flags).
When pressing C-c C-s, the command LaTeX-section (found in LaTeX-mode-map, defined in latex.el) offers to enter a label for the section, with no suggestion (other than a prefix based on the level of the section, which is useful but much less than the one based on the title section offered by reftex-label).
How can one configure LaTeX-section to make the same suggestions as reftex-label for sections?
The hook LaTeX-section-hook along with the variable LaTeX-section-label would seem the right candidate for that purpose, but the documentation states that
Some LaTeX packages (such as fancyref) look at the prefix to
generate some text around cross-references automatically. When using
those packages, you should not change this variable.
for one, I assume that reftex is one of such packages, and second, I was expecting to be able to give a function inside a hook, not a list of prefixes, I wonder if I misunderstood what a hook is?
I think that one would "just" need to get LaTeX-section to abstain from offering a label and to call the function reftex-label immediately after each LaTeX-section call, but if it is not LaTeX-section-hook, I do not know which one it could be?
Before starting programming something which could involve stuff as complicated as refactoring both latex.el and reftex-ref.el, I thought I would ask in case I was missing an easier solution!!!

Any way to manually trigger highlighting of semantic symbol occurrence in Visual Studio Code?

In VSCode, when you place cursor inside a symbol (variables, functions, etc), all occurrence of the same symbol will be highlighted.
This feature is somewhat useful but annoying as well. Even I can make it less obtrusive by customizing the color theme in settings.json, it will suppress the selection highlighting when you select a variable by double clicking it with mouse cursor.
I've learned that I can completely disable this feature by adding "editor.occurrencesHighlight":false in settings.json, but this feature is still useful because it can label occurrences of a symbol with different color, to represent read/write status of each occurrence.
So my question is: is there any way to disable the automatic semantic matching feature, and only enable it manually with keyboard shortcuts or commands ?
If you only need textual matches, you can select some text use the Select all occurrences of find match command. This will select every occurrence of the selected text in the current document (and also create a cursor at it)
For symbol based information, try using the Find all references or Peek references commands. The flow is different but it gives the same information.
Alternatively, use an extension like this one to create a keyboard shortcut that toggles editor.occurrencesHighlight

VS Code Refactoring: Change all occurences - but only in block scope

When using "change all occurences" in VS Code, it will just search the whole file for matches and change them. Is there a similar feature doing the same thing, but limiting it to function or block scope?
Let's take an example where I would need that: I'm having a React file with several components and want to refactor a class component to a functional component, so I'm changing all occurences of this.props to props. However, I obviously don't want to change all the other class components as well that are supposed to stay class components. :-)
This seems like such a standard use case, but I'm not able to find it anywhere in VS Code. If it's not possible (yet, or for some good reasons) is there another way to achieve what I'm trying to do?
Check out the 'Add Selection To Next Find Match' functionality. It allows you to highlight the first occurrence you'd like to change, then using a keyboard shortcut, highlight the next occurrence and so on until you've selected all the instances you want to change. When all to-be-changed occurrences are selected, you can edit the selected text normally. Just remember to hit the escape key a couple times after editing to return to a single cursor!
Here are the keybindings for the command, it's Cmd+d on Mac:
https://code.visualstudio.com/docs/getstarted/keybindings
I find it very useful when renaming variables, there's also a shortcut to skip occurrences (Cmd+k Cmd+d) in case there is text you don't want to change in between.

CodeMirror highlighting on find

I want to recreate the find function in CodeMirror for highlight each occurrence like showed in this demo.
I have created an example using marks, but highlight only the first occurrence.

Changing your if (cursor.findNext()) to while (cursor.findNext()) might already get you somewhere. It is more efficient (though also a little more complicated) to use an overlay instead, which is what the built-in search functionality does.

How do I modify text while keeping the original fontification?

I'm writing a mode which is actually a glorified markdown reader. It's a read-only mode however, and though I'd like to change the faces for bold, italics, and links, I'd love to remove the decorations surrounding those faces. However, when I do so, I lose the fontification. Is there anyway to modify fontified-text to something that no longer matches any of the syntax regexes and still keep the fontification?
Org-mode does this for its link markup. I'm not a mode writer (yet), but Org-mode would be the first place I'd look for code that demonstrates how to do this. Oddly, it doesn't do it for any of its fontification: italic, bold, and underline all retain their markup.
Specifically, the code to hide the link markup is on line 4612 of org.el in version 7.01 of org-mode:
(if org-descriptive-links (add-to-invisibility-spec '(org-link)))
where add-to-invisibility-spec is actually supplied by a built in elisp file subr.el, and allows specific types of markup to be hidden. That would be the approach I would take, especially if the buffer is read-only.
