How to open meshes list?

I think i clicked something or thats just 282 feature that i installed few days ago… but i cant click this arrow to see all my meshes, only can see their list by clicking orange triangle

how to fix it back ?
sorry for such dumb question :slight_smile:

PS vid about what exactly i mean

on 279 and 280 everything ok

281 282 283 is not working

PS fixed, something wrong was with keybindings, after reseting them on default things start working
