In Impress, if you click a slide in the slide pane and then use Shift + Arrow Up/Down, then the slides are selected. However, Shift + Home/End does not select the slides. It only goes to the first/last slide, without selecting anything. So I'd like to propose that Shift + Home/End in the slide pane selects the slides as well (starting from the current slide up to the first/last slide). This is useful in large presentations. For instance, suppose I have a file with 50 slides and I want to remove all slides starting at slide 15. Then I could simply click slide 15 and then use Ctrl + End to select the remaining slides up until slide 50 and then delete them. This use case is very common when preparing lectures, because we get a "template" file and then want to keep only the first slides and remove the rest.
