Menu Bar
========
The menu bar at the top of the *SasView* window gives you access to additional features of the program:

File
----
The File option allows you load data into *SasView* for analysis, or to save the work you have been doing.

Data can be loaded one file at a time, or by selecting multiple files, or by loading an entire folder of 
files (in which case *SasView* will attempt to make an intelligent guess as to what to load based on the 
file formats it recognises in the folder!). Data can also be loaded by dragging and dropping files directly
onto Data Explorer.

A *SasView* session can also be saved and reloaded as an 'Analysis' (an individual model fit or invariant 
calculation, etc), or as a 'Project' (everything you have done since starting your *SasView* session).
Finally, a session can be closed so a new project can be created. This will clear all plots, data and
content in all the perspectives, even those which are not currently visible.

Edit
----
The Edit option allows you to:

- copy and paste parameters between *SasView* analysis windows;
- copy parameters from a *SasView* analysis window to the Clipboard as either tab-delimited text (compatible with Microsoft Excel) or LaTex-wrapped text;
- generate a summary 'Report' of the most recent analysis performed;
- reset parameter values in the P(r) Inversion analysis page;
- freeze/copy fit results as separate data sets.

View
----
The View option allows you to:

- show the Batch Fitting Results Panel if it has been closed;
- show/hide the Toolbar of icons below the Menu Bar;

Tools
-----
The Tools option provides access to a comprehensive range of tools and utilities. See :ref:`tools` for more information.

Window

The Window option allows you to select which *SasView* windows are visible;

- enable window cascading/tiling;
- move focus between windows both forward and backward;
- minimize all plot windows;
- close all plot windows;
- access plots by name;

--------
The Analysis option provides access to the key functionality of *SasView*:

- Model Fitting;
- P(r) Inversion;
- Invariant Analysis;
- Correlation Function Analysis (*SasView* 4.1 and later)

See :ref:`analysis` for more information.

Fitting
-------
The Fitting option allows you to:

- create a new FitPage;
- setting up a Constrained or Simultaneous Fit;
- change optimiser (under Fit Options);
- view fit parameter correlations, distributions, and convergence traces (under Fit Results);
- manage model categories;
- create a Plugin Model;
- edit a Plugin Model;

Help
----
The Help option provides access to:

- information about the version of *SasView* you are using;
