slow_blink timeout customization

[cyberdynesoftware]

In my color theme, I have configured the match of a parenthesis to blink:

"ui.cursor.match" = { modifiers = ["slow_blink"] }

Now when moving the cursor to a parenthesis, the matching parenthesis starts blinking and stops blinking about 15 seconds later. My question is: where is this timeout defined? Am I able to customize this?

Blinking is a terminal feature. It is being set with CSI 5 m for 'slow_blink' and CSI 6 m for 'rapid_blink'. How exactly this is working depends on terminal implementation.

For example, foot doesn't stop blinking, while ghostty and alacritty do not blink at all. Refer to your terminal documentation, Helix doesn't control that.
