<para
>Window, View, Document, Frame, Editor... What are they all in the terminology of &kate;, and how do you get the most out of it? This chapter will explain all of that, and even more.</para>

<title
>The Main Window</title>

<para
>The &kate; Main Window is a standard &kde; application window, with the addition of dockable subwindows, or tool windows. It has a Menubar with all the common menus, and some more, and a toolbar providing access to commonly used commands.</para>

<para
>The most important part of the window is the Editing Area, by default displaying a single text editor component, in which you can work with your documents.</para>

<para
>The docking capabilities of the window is used for the tool windows:</para>

<para
>And possibly other tool windows, for example provided by plugins.</para>

<para
>The Tool Windows can be placed anywhere you want them inside or outside the main window by dragging the handle bar in the top of them with the &LMB; pressed, and stacked in shared tab windows if desired.</para>

<para
>When dragging a docked window, a black rectangle will be displayed to indicate where the window will be placed if you release the mouse button, unless you move the mouse cursor outside the main window, in which case the dragged window will become a free floating top level window.</para>

<sect1 id="kate-mdi-editor">

<title
>The Editor area</title>

<para
>&kate; is capable of having more than one document open at the same time, and also of splitting the editing area into any number of frames, similar to how for example &konqueror; or the popular <application
>emacs</application
> text editor works. This way you can view several documents at the same time, or more instances of the same document, handy for example if your document contains definitions in the top that you want to see often for reference. Or you could view a program source header in one frame, while editing the implementation file in another.</para>

<para
>When a document is available in more than one editor, changes made in one editor will immediately be reflected in the others as well. This includes changing the text as well as selecting text. Search operations or cursor movement is only reflected in the current editor.</para>

<para
>It is currently not possible to have more instances of the same document open in the sense that one instance will be edited while the other will not.</para>

<para
>When splitting an editor into two frames, it is divided into two equally sized frames, both displaying the current document of that editor. The new frame will be at the bottom (in the case of a horizontal split) or at the right (for a vertical split). The new frame gets the focus, which is visualised by a small green led in the focused frame.</para>

</sect1>

<sect1 id="kate-mdi-tools-file-list">
<title
>The File List</title>

<para
>The file list displays a list of all documents currently open in &kate;. Modified files will have a small <guiicon
>floppy disk</guiicon
> icon on their left to indicate that state.</para>

<para
>If two or more files with the same name (located in different directories) are open, the names of the second will be prepended <quote
>&lt;2&gt;</quote
> and so on. The tool-tip for the file will display its full name including the path, allowing you to choose the desired one.</para
> <para
>To display a document in the currently active frame, click the document name in the list.</para>

<para
>The default location in the &kate; window is to the left of the editing area, in a dockable tab window shared with the <link linkend="kate-mdi-tools-file-selector"
>File Selector</link
>.</para>
</sect1>

<sect1 id="kate-mdi-tools-file-selector">
<title
>The File Selector</title>

<para
>The File Selector is a directory viewer, allowing you to open files from a displayed directory in the current frame.</para>
