[newbie] can't figure out the LSP / object mode

I’m having trouble figuring out how to use the mappings for kak-lsp. The documentation recommends using object mode mappings but I don’t quite get them.

For example, for this keybind:

map global object d '<a-semicolon>lsp-diagnostic-object --include-warnings<ret>' -docstring 'LSP errors and warnings'

I am expecting to recieve some sort of message on the error i’m highlighing. So I run:

<a-a>d

But that only selects the word I’m at. Pressing d again deletes it. I don’t understand object mode mappings and trying to map it to something like makes the lsp tell me that there’s nothing selected, so I believe it must be done through object-mode.

I am using the same configuration that the kak-lsp documentation recommends:

map global user l ':enter-user-mode lsp<ret>' -docstring 'LSP mode'

map global insert <tab> '<a-;>:try lsp-snippets-select-next-placeholders catch %{ execute-keys -with-hooks <lt>tab> }<ret>' -docstring 'Select next snippet placeholder'

map global object a '<a-semicolon>lsp-object<ret>' -docstring 'LSP any symbol'
map global object <a-a> '<a-semicolon>lsp-object<ret>' -docstring 'LSP any symbol'
map global object f '<a-semicolon>lsp-object Function Method<ret>' -docstring 'LSP function or method'
map global object t '<a-semicolon>lsp-object Class Interface Struct<ret>' -docstring 'LSP class interface or struct'
map global object d '<a-semicolon>lsp-diagnostic-object --include-warnings<ret>' -docstring 'LSP errors and warnings'
map global object D '<a-semicolon>lsp-diagnostic-object<ret>' -docstring 'LSP errors'

Hello,

There are more more mappings than just the object mappings. The object
mode mappings essentially let you select text in your document based
on output from the LSP. So, the <a-a>d binding selects the part of
your code the diagnostic is applied to
. To see the text contents of
the diagnostic, you can use the lsp-hover command, which by default
is bound to <space>lh.

As a general rule, object mappings help you select stuff. The other
mappings, in the lsp user-mode, help you do other things.
