I was working the sectors 73/53/54 combined with a low to average traffic complexity. I looked to the northeastern section of my sector which is adjacent to Sector 74 (Charleston sector); this sector was combined with Sector 71 (Flourence). I observed a PVD on my scope with the callsign of Air Carrier X. The aircraft was inside my sector boundary and I noticed the altitude of the aircraft leaving 11;000 FT climbing to FL230 in the Data Block. I was working with a RADAR Associate at the time of the incident. I ask the RADAR Associate if they had received a point out on the aircraft and their answer was no. Have the controller working Sector 71/74 complete his pointout by calling the sector and advising them he will be climbing aircraft in their airspace so that safety is not compromised.
ZJX Controller described an airspace infraction when an adjacent sector manipulated the data block without any verbal coordination.
