Showing help about commands

I tried to see the help of a command, placing the cursor over the command and using shift-tab, but it doesn’t work. Is there a different command or I must activate trough settings, if so how?

I think you are using the web version shift-tab wont work there .In the desktop version shift-tab works.
@bollwyvl,@fomightez correct me if i am wrong.

shift-tab only works for me after at least one cell has been executed.

for me it’s working without cell execution.

This could be the case if the kernel is lazy initialized only after first cell execution (which depends on user settings and kernel in question).

“web version” is ambigious term. In general it should work in standard JupyterLab (“web”) and in JupyterLab Desktop when using a kernel which supports inspect messages. I do not know about JupyterLite (also “web”) which may indeed require waiting for the kernel initialization which takes longer there (and would functionally be synonymous with waiting for the first cell execution).

4.2.0 has an issue with this, it seems. See krassowski’s comment here that links to a filed issue here, that is presently open.
