Highlight same words

[nguyencraft01]

Hi
I'm using Code::Blocks 20.03 in window 7. When I double click a word, Code::Blocks editor must be highlight all the other same words in red shape like this picture. But on my version, it didn't. This feature is very helpfull, it show where I didn't fix the variables. How can I enable highlight same words feature in Code::Blocks 20.03 for window 7.

Check if the plugin Occurences Highlighting is installed, and enabled:
Settings->Editor->Occurences Highlighting->Highlight occurences of selection

If the plugin is not intsalled try a nightly build

Can you recommend a stable nightly build? And how to install it?

Nightly builds are mostly (>95%) stable.
To install it follow the instruction in the nightly build post
