 For all the buttons, you have a counterpart on the menu bar, but the opposite is not true. The letter in the parenthesis shows the short key to the same action, once you click on the image. A full set of all actions is also available on the terminal. 
 
- 1. Change Mask: Generally, when drawing a new region to mask the image, it would be applied on all band, and its easier to look at the composite image (however you can still choose to look at other band and edit the common mask file). If a band is selected (and not a composite image), then you will have an opportunity to generate masks for the chosen band. The file that contains each band mask is sto[[span(style=color: #FF0000,  red )]] separately. Under this button, you will see the status of the masking.

  Current: All Bands: the generated mask would be used for all bands and it is displayed with Green color.

  3. Undo Region: Removing the last added region. Currently this only works for common regions, i.e. green masks.
  
- 4. Remove a region: After clicking on this button you need to lick inside a region to remove it. This works for both band-masks and common-mask (i.e. Green and Pink regions). If the regions does not exist (in case of any mistake), the action would be igno[[span(style=color: #FF0000,  red )]].

  5. Clean all regions: After user verification, it removes all the region. This works for both band-masks and common-mask (i.e. Green and Pink regions).
   
- 6. Save region: Normally all common-regions (Green reg.) would be saved after doing the measurement. However, once can save any change before doing the measurement. This is helpful when working with big galaxies. One should note that all band-masks are sto[[span(style=color: #FF0000,  red )]] instantly and users should not be worried about saving their pink masks. This is because, we don not expect to have a lot of masking for each individual mask.

- 10: ds9: Opens the fits file of the displayed image in the TV. If not band has been specified (in case of using the composite image), the use-file ('r' band for /sdss and /panstarrs) would be opened. In ds9, one can play around with the '[[span(style=color: #FF0000,  red )]]' elliptical aperture, (e.g. re-center it, or resize it).

- 12: Import Ellipse: To import the '[[span(style=color: #FF0000,  red )]]' aperture from ds9 to the TV (when ds9 is open). All ellipse information would be updated and be used for the measurement. Note: ds9 can also be used a bridge between Pylipes (i.e. the python code to modify the ellipse) and GLGA TV. However, Saving (in Pylipse) and loading (in TV: Menu > Pyliupse > Load Ellipse) is a way to import from Pylipse to GLGA TV.

  14: Run SExtractor: Running SExtractor to update the ellipse information. If SExtractor has been already run and the information exists in the data-base, the GUI asks whether to use the previous results, or run SExtractor again. Note: one can run SExtractor automatically for the entire data-base, and if there is any adjustment needed, it is possible to re-run it in the TV. In this case, TV first creates a temporary masked image (applying both band-mask and common-mask files) and then runs SExtractor. This way one can take care of any foreground/background problems that could have been already resolved. Also there are other masking options just to run SExtractor (see: menu > SExtractor)
 
- 15: Edit Ellipse: Editing the ellipse parameter in the TV. To see all the options, look at the terminal and follow the right commands. Note: if in the middle of the editing, user clicks on any button on the control-panel, the ellipse editing action would be igno[[span(style=color: #FF0000,  red )]] and the new command would be run.
