In the blender outliner, the shortcut H is used for hide a layer, but there isn't any shortcut for unhide a specific layer, only Alt+H for unhide all. I want to know why not just use H for toggle a layer? So that we can use H for hide and unhide a layer. It can be more convenient for all artist. Hope blender developer can see my advice and improve the function.

  • $\begingroup$ @DuarteFarrajotaRamos Which version are you on? If I have let's say three collections and hide two with H, then Alt+H unhides both. $\endgroup$ Aug 11, 2022 at 13:55
  • $\begingroup$ @GordonBrinkmann Indeed you are right it does unhide all. $\endgroup$ Aug 11, 2022 at 14:11
  • $\begingroup$ @DuarteFarrajotaRamos Thank you very very much for your advice and link, that's really help me. I'm a fresh bird in blender, please forgive my a dime-a-dozen idea. $\endgroup$

By default in Outliner keymap H is mapped to Outliner Hide operator outliner.hide, but Alt + H is mapped to Unhide All with operator outliner.unhide_all.

By going to the outliner keymap at Edit > Preferences > Keymap > Outliner you can change the keymap of Alt + H to the command Show Collection with operator outliner.collection_show
