HELP page states ctrl+space+shift Replay audio slower

but that doesn't work, what you need to do is

ctrl + shift and THEN after a second hit space

If you just click ctrl + space + shift or ctrl + space , wait a sec.. then shift, you get fast audio - because there is a bug - as soon as the program recognizes ctrl + space, it doesn't seem to wait for the next key.

Simple to fix. Thanks.
