The main menubar has various sub-menus for program and trace-group operations.
_______________________
"File -> Open File..." - read trace files from local file system and display in a new trace-group
"File -> Open Web Location..." - read trace files over the Internet and display in a new trace-group
"File -> Open SeedLink..." - create a connection to a SeedLink server and display specified streams in new SeedLink Monitor trace-groups (see: SeedLink Monitor)
"File -> Open Trace Browser..." - use internal SeisGram2K browser to read trace files locally or over the Internet and display in a new trace-group
"File -> Open Bud dir..." - use internal SeisGram2K browser to read IRIS-Bud directory channel files locally or over the Internet, display in a new trace-group with automatic scrolling through files for the same channel(s) in the Bud directory
"File -> Close Active" - close the active trace-group (also available through the "X" button to the upper right of the trace-group window)
"File -> Close All" - close all trace-groups
"File -> Open LiveSeis..." - opens a LiveSeis session (LiveSeis is no longer supported in SeisGram2K)
"File -> Save Active As..." - write to disk file(s) the current time window of the active trace-group
"File -> Duplicate Active" - create a new trace-group containing the current time window of the active trace-group (also available through the "=" button to the lower right of the trace-group window)
"File -> Reset Active" - reset active trace-group data to state before any processing (the data traces are stored when the first mathematical processing action is applied)
"File -> Print" - print all trace-groups or active particle motion view
"File -> Snapshot" - saves screen snapshot of trace-groups window or active particle motion window
"File -> Export Picks" - save picks to a disk file
"File -> Exit" - exit SeisGram2K
_______________________
"View -> Particle Motion" - open a particle motion view for the active trace-group
"View -> Spectrum" - open a spectral view (amplitude vs. frequency) for the selected trace in the active trace-group
"View -> Spectrogram" - open a spectrogram view (frequency vs. time) for the selected trace in the active trace-group
"View -> Helicorder" - display seismograms in multi-line, helicorder mode
"View -> Number Trace Groups..." - set the maximum number of trace groups to display before scrolling
"View -> Seismogram Info" - displays the header information for the active trace (also available through the "i" button to the lower right of the trace-group window)
"View -> Full Window" - toggles display of the active trace-group in the full SeisGram2K window (also accessible with a button to the right of the Viewing Toolbar)
"View -> New SG2K Window" - launches active trace-group in a new SeisGram2K window (also accessible with a button to the right of the Viewing Toolbar)
"View -> Align to..." - align time windows of all trace groups and set time windows to the same width
" ... -> Active" - align time window of all trace groups to current time window of active trace-group (gives common time base)
" ... -> Global Min->Max" - align time window of all trace groups into smallest time window containing all data from all trace groups (gives common time base)
" ... -> Start" - align time windows to start time of each trace-group (gives independent time bases)
" ... -> Origin Times" - align time windows to origin time (if available) of first seismogram in each trace-group (gives independent time bases)
" ... -> Last Data" - align time windows to last data received (LiveSeis, SeedLink, etc. monitor mode)
" ... -> Realtime" - align time windows to current realtime (LiveSeis, SeedLink, etc. monitor mode)
"View -> Lock Alignment" - toggles locking of current trace-group time alignment; when locked, the relative time window alignment of all trace groups is maintained with respect to changes the time window of the active trace-group (also accessible with a button to the right of the Viewing Toolbar)
"View -> Align Amp to..." - align amplitude range of all trace groups
" ... -> Active" - align amplitude range of all trace groups to current amplitude range of active trace-group (gives common amplitude base)
" ... -> Global" - align amplitude range of all trace groups to min/max amplitude range of all trace groups (gives common amplitude base)
" ... -> Initial" - align amplitudes of all trace groups to their initial amplitude ranges =
" ... -> Window" - align amplitude range of each trace groups to the min/max amplitude in current time window
"View -> Time Axes" - toggles display of trace-group time axes
"View -> Sort" - sort trace groups by selected header value, if value availabe for data
"View -> Viewing Toolbar" - toggles display of the Viewing Toolbar
"View -> Analysis Toolbar" - toggles display of the Analysis Toolbar
"View -> Message Window" - toggles display of the Message Window
"View -> Select Panel" - toggles display of the Selection Panel to the right of each trace-group window
"View -> Realtime Toolbar" - toggles display of the Realtime Toolbar (LiveSeis, SeedLink, etc. monitor mode)
"View -> Origin Time" - toggles display of a marker (pick) showing event origin time (if available in trace header)
"View -> Invert Colors" - toggles seismogram colors between normal and inverted/reverse
"View -> Grey Scale" - toggles seismogram colors between colored and greyscale
"View -> Anit-alias" - toggles rendering using anti-aliasing (smoothing) in trace-group window; anti-aliasing can increase CPU load significantly
_______________________
"Insert -> Syntetic Trace..." - insert a new trace-group with specified synthetic trace data
_______________________
"Utilities -> Language..." - change the user interface language
"Utilities -> Header Editor..." - edit the trace header meta-data
_______________________
"Presets" - Preset processing commands (specified in the "commands.preset=" program parameter, see Running, arguments -> Specifying Preset menu command)
_______________________
"Help -> Help" - displays this program help window
