Thanks, that did the trick. I added a search for the category I put my addon in, and I guess that's close enough:
Lua Code:
if (not KeyBindingFrame) then
KeyBindingFrame_LoadUI()
end
if not InCombatLockdown() then
KeyBindingFrame:Show()
for _,v in pairs(KeyBindingFrame.categoryList.buttons) do
if v:GetText() == "AddOns" or v:GetText() == "ADDONS" then
v:Click()
end
end
end
