When you double click on a word, the other instances do not highlight due to the Find Box being open
When I am using Quartus and I happen to have the Find Box open and nothing is in it and I double click on a word in a file, the other instances will not highlight due to the fact that I have the Find Box open. You must close the Find Box before the other instances of a word will highlight again.
Specs:
OS = Windows Enterprise 11
Software = Quartus Prime Version 25.3.0 Build 109 09/24/2025 SC Pro Edition
Patches Installed = 0.27
Steps to recreate
1. Open Quartus program
2. Open a file (HDL or Verilog, doesn’t matter)
3. Left double click on a word within the file and observe how other instances are highlighted
4. Open the Find Box (Ctrl+F)
5. Remove any word that is in the Find Box
6. Left double click on a word within the file expecting other instances to be highlighted
7. Observe that they are not highlighted due to the fact that the Find Box is still open
8. Close the Find Box
9. Left double click on a word within the file and observe how other instances are highlighted again now that the Find Box is closed
This is a bug with the functionality of the Find Box.

It's been like this forever. I don't see that getting fixed any time soon.
There's another recent post here or in another of the forums about Text Editor issues.

I make a comparison between this case and the previous one:
Table 1:
https://community.altera.com/discussions/quartus-prime/highlight-similar-instances-of-a-selected-word-fails-when-scrolling/337284/replies/350951
Aspect
Your Original Issue (selection jump & mass deletion risk)
Find Box state
Closed with non‑empty search term left in it
Trigger
After closing Find, start selecting (click‑hold‑scroll) or scroll with wheel
Observed behavior
Scroll re-selects previous Find term- Click‑hold‑scroll selection can jump to top (unintended large selection) → risk of mass deletion
Table 2:
https://community.altera.com/discussions/quartus-prime/when-you-double-click-on-a-word-the-other-instances-do-not-highlight-due-to-the-/351004
Aspect
New Steps (double-click doesn’t highlight when Find is open & empty)
Find Box state
Open and empty
Trigger
Double‑click a word expecting “highlight all instances”
Observed behavior
Double‑clicking a word does not highlight other instances while Find box is still open- Once Find is closed, highlight‑all behavior returns.
Let me know if this is incorrect, can you also send us the video for this issue?
Please note that I have reported the table 1 bug to engineering to fix it.
Thanks, Kenny
