It is also used to filter 0xe025 key code which is generated by 3rd key and is
visible via both atkbd and wmi:
===
343 if (type == 0x0000 && code == 0xe025 && !wmi_requires_smbios_request)
344 return;
===

Likely, yes. At least, for Launch Manager (key "3") there is a record in the
table:
===
135 /* Dell Instant Launch key */
136 { KE_KEY, 0xe025, { KEY_PROG4 } },
===
As for Mobility Center, relevant key is commented out and has completely
different keycode:
===
150 /* Untested, Windows Mobility Center button on Inspiron 7520 */
151 /* { KE_IGNORE, 0xe02a, { KEY_RESERVED } }, */
===
For Support Center, it is not commented, but still reserved:
===
189 /* Dell Support Center key */
190 { KE_IGNORE, 0xe06e, { KEY_RESERVED } },
===

So, according to what I see above, it looks like KEY_PROG(X) pattern should be
followed.

Just to note what I did. Here is my custom /etc/udev/hwdb.d/90-dell-
vostro-3360.hwdb:
===
evdev:atkbd:dmi:bvnDellInc.:bvrA18:bd09/25/2013:svnDellInc.:pnVostro3360:pvr:rvnDellInc.:rn0F5DWF:rvrA00:cvnDellInc.:ct8:cvr0.1:
KEYBOARD_KEY_60=prog4
===
Here is how this key press is being detected by evtest via atkbd:
===
Event: time 1511289883.083968, type 4 (EV_MSC), code 4 (MSC_SCAN), value 60
Event: time 1511289883.083968, type 1 (EV_KEY), code 203 (KEY_PROG4), value 2
Event: time 1511289883.083968, -------------- SYN_REPORT ------------
===
But xev shows nothing when I press this key. Am I doing something wrong?

Well, sounds reasonable...
Thanks.
