Guidance for learning

To become familiar with MetaEdit+:
1)Read Chapter 1 to familiarize yourself with the MetaEdit+ environment and its basic functionality. This part of the manual is best read while sitting at your computer so that you can experiment with the features of MetaEdit+ as they are described in the text.
2)Read Chapter 2 get a more detailed overview of the environment and its features and capabilities.
3)Skim the components chapters (Chapters 3, 4 and 5), once you have completed the two first chapters and gained some experience with MetaEdit+. These chapters contain in-depth information about each of the tools that you used in the tutorial: you do not need to know everything here, but it is useful to have a basic idea of what information is covered where.
4)For more detailed description about the repository solution and meta-metamodel of MetaEdit+, see Chapter 6.

MetaEdit+ is a dynamic product under continual improvement, and there may occasionally be some differences between what is described in the manual and what is found in the current version. The latest versions of the manuals are available from MetaCase.

Conventions

Throughout the manual, you will find special notes and comments which point out important features and characteristics of the MetaEdit+ environment. These notes are printed in italics and are marked by an arrow (→) in the left margin. The steps required for performing MetaEdit+’s various functions are indented and numbered: 1), 2), 3) etc.

List dialogs and keyboard search

MetaEdit+ makes extensive use of list dialogs for selecting among elements. To quickly select a known element in a list, simply type the first few letters of that element’s name when the dialog opens. This moves the cursor to the first element whose name begins with those letters. Pressing Enter will choose the current framed element, closing the dialog. Pressing Space selects the current framed element, and resets the typed buffer, so you can start typing a different name. You can also double click an element to choose it and close the dialog.

To move to the next matching element, press Alt+Down, or Alt+Up/Home/End for the previous/first/last match. To include a Space in the search string (or other reserved character like Enter, or *, +. – for tree widgets), hold down Alt while you type the character. Searching like this also works in the focused widget elsewhere: lists, trees, property tree sheets and Table Editor (but not other multi-column data sets).

Some dialogs allow multiple selections: use Shift-click or Shift-space to select a contiguous section of the list, and Control-click or Control-space to select or deselect individual elements. Again, a double click first performs the selection operation (modified by Shift or Control keys), and then closes the dialog.

The Windows user interface standard prevents resizing of modal dialogs, which can make life difficult if all the necessary information is not visible in the default size. To help in such situations, MetaEdit+ includes a triangular resize corner at the bottom right of most dialogs. By clicking and dragging the resize corner, you can resize the dialog window to be larger.
