I find it inconvenient to have to hunt for the little volume icon in the bottom right, then have to hunt for the little slider knob, drag it and press enter. More so because sometimes I want to change the volume while I'm exercising with glasses off.
I like the option to change the volume with Fn+F4/Fn+F5 which my laptop provides, but it changes very slow, I need to hold the keys for a long time.
What I'd love is an app that lets me press Win+V to open a small window (similar to Launchy) which only waits for me to press a single 0-9 digit on the keyboard for 0-100%. E.g. 5 could be 50%. And autocloses after I press a digit.
Alternatively, press Win+V which creates something like a full screen slider waiting for me to simply move my mouse to the desired position and press enter.
Edit: I found Volumouse but haven't tried it yet.
