RStudio autocompletion for Shiny input and output objects

[RN]

Is there a way / trick to get RStudio to autocomplete on the shiny objects like input$foo or output$bar like the way it will autocomplete "regular" objects like fooobject$barcolumn?

I use RStudio a lot and as the size of the shiny application becomes larger this would help me during coding a lot to avoid silly typos etc. 

Any tips? Ideas?

If you develop your shiny app using the two-file structure (server.R and ui.R) as opposed to just using app.R, then newer versions of RStudio *should* autocomplete inputs and outputs

Thanks Dean. I will try that. So far I had a single file. 

Any idea why the autocomplete gets suppressed in a single file scenario? Just a bug or some other reason?
