Prevent the x in \frac{x}{} to become xcolor when typing Tab.

[jademath]

In the default settings, when I input \fr, press Tab, type x, and then press Tab again, the system auto-completes x to xcolor. This is not the desired outcome because my intention is to use Tab to move to the next set of braces. I found a workaround by enabling 'tab completion' and simultaneously disabling 'quick suggestions'. This solution is almost perfect, except for one issue: typing beq followed by Tab no longer works. Instead, I have to type BEQ (in uppercase) followed by Tab to create the desired environment.

Ideally, I'd like to have 'quick suggestions' enabled only for snippet keywords, such as beq, mbf, and so on. However, I am unsure how to achieve this. While there is an option to enable 'tab completion' for snippets only, a similar option for 'quick suggestions' seems to be lacking.

A quick fix I can think of is to define both upper and lower-case snippets. Is this already implemented?

You document most likely contains the word xcolor. Typing x inside \frac{}{} triggers quick suggestions and hitting TAB accepts the currently selected quick selection. The are two ways to tweak this behaviour

• Set editor.suggest.snippetsPreventQuickSuggestions to true to prevent quick suggestions to show up when a snippet is already active.
• You can also play with editor.suggest.selectionMode to decide when you want a snippet to be automatically selected when a suggestion list shows up.
