and then press

Shift-M

will give some idea.

You can get a buttload of good info on a particular process from its 
Process ID number.  Eg, for PID 18053

cat /proc/18053/status

Name:   ekiga
State:  S (sleeping)
SleepAVG:       97%
Tgid:   18053
Pid:    18053
PPid:   3249
TracerPid:      0
Uid:    500     500     500     500
Gid:    500     500     500     500
FDSize: 256
Groups: 14 500
VmPeak:   118920 kB
VmSize:   118432 kB
VmLck:         0 kB
VmHWM:     23592 kB
VmRSS:     23292 kB
VmData:    18504 kB
VmStk:        84 kB
VmExe:       900 kB
VmLib:     35996 kB

Cpus_allowed:   ffffffff
Mems_allowed:   1

For all these though, understand that shared libs get counted for every 
process, exploding the total figures given for all processes compared to 
actual global memory usage.
