after researching, I found that when running "Telescope aerial", the cursor by default starts on the nth item related to nth function your cursor located. it should be starting on last(bottom) item. because last item is most matched item.

[stevearc]

The cursor starts on the current symbol, and the symbols are ordered the same way they are in the file. Once you start typing and the number of results changes, the cursor jumps to the last item. This all seems correct to me.

Is your request to have the cursor start on the last symbol in the file, regardless of where your current cursor position is?

[yimingwangdell]

@stevearc sometime it didn't work. if I type only one character, there is no preselected item at bottom. then if I type \<up> to preselect one item, it was not the last one.

I think that what is happening is that telescope only moves the cursor to the bottom after the total number of results displayed has changed. If you type a single character that doesn't filter out any of the results, the cursor will stay somewhere in the midpoint. Is this the behavior you are seeing? This is arguably a bug in telescope since that is probably not intentional behavior, but it also is generally not an issue in practice since typing two characters is usually enough to filter out at least one result.
