In English, «Reload» and in Spanish «Recargar», under the menu File inside de application Math : they do not have a hotkey in the UI.
Reproducible with LO 18.104.22.168, Win 8.1
Thanks for your bug report!
Lots of menu items don't have shortcuts, so this isn't a bug per se.
Let's make this an enhancement request
-> Severity: enhancement
-> Platform: All
Adolfo: what hotkey to put? Are there some standards? (BTW, Ctrl+R is already used)
I checked the other apps, not hotkey too for "Reload" commands.
Also Matthew is right, it's not the only command which doesn't have an hotkey.
OK, I now realize we used the wrong word, this bug is about a missing *accelerator*, or underlined letter. Apologies!
