I am using Ubuntu 16.04 with Unity desktop, sound system is pulseaudio.
I want to have custom shortcuts to change volume, in addition to media keys "audio lower/audio upper".
I created custom shortcuts that call commands pactl set-sink-volume 0 -5% and pactl set-sink-volume 0 +5%. But unlike media keys, this shortcuts change volume without visual indication.
What is command to change volume and display it's visual level indication, like it works with media keys?

Unity as other Gnome-based desktops havedbusand there is adbusmethod, which you can call to change audio and the change ondbustells Unity to show the popup. But it's been awhile since I've used Unity. If I get around to using Unity again or dig out my old scrips, I'll post an answer some time. Otherwise, Martin's answer is good enough to get the job done.

Interesting. I know that PulseAudio clients control the server though DBus. Gnome/Unity heavily use the DBus so it would not surprise me to learn that there is a way to trigger the media OSD by DBus, but I don't know it.

Unity as other Gnome-based desktops have
dbus and there is a dbus method, which you can call to change audio and the change on dbus tells Unity to show the popup. But it's been awhile since I've used Unity.

You should able to map XF86AudioLowerVolume and XF86AudoRaiseVolume to whatever custom key sequences you wish using the usual keymapping configuation tool, in addition to your already dedicated media keys. There is no restriction on a unique mapping.
Another possible command line solution is to use xdotool This tool lets you simulate keyboard input using the X11 XTEST extension. E.g. after installing the package, you should be able to use the commands:
xdotool key XF86AudioLowerVolume
and
xdotool key XF86AudioRaiseVolume
to do what you want.

That's an ingenious workaround, but it doesn't work for me :( From console xdotool works fine, volume is changed and indication appears. But when I assign this command to hotkey, nothing happens :( I tried using full path /usr/bin/xdotool and even made a wrapper script to see what's going on, but script shows that the command worked fine and returned 0. I think this is some Unity bug, that disallows global hotkey handling while other global hotkey is processed.
