Word wrap is a feature that causes the editor to automatically start a new line of text and move (wrap) the cursor to the beginning of that new line. KWrite will automatically start a new line of text when the current line reaches the length specified by the Wrap Words At: option.
If the Word Wrap option is selected this entry determines the length (in characters) at which the editor will automatically start a new line.
KWrite will replace any tabs with the number of spaces indicated in the Tab Width: entry.
If the Replace Tabs By Spaces option is selected this entry determines the number of spaces with which the editor will automatically replace tabs.
KWrite will automatically eliminate extra spaces at the ends of lines of text.
When the user types a left bracket ([, (, or {) KWrite automatically enters the right bracket (}, ), or ]) to the right of the cursor.
The editor will display a symbol to indicate the presence of a tab in the text.
This option changes the behavior of the cursor when the user presses the Page Up or Page Down key. If unselected the text cursor will maintain its relative position within the visible text in KWrite as new text becomes visible as a result of the operation. So if the cursor is in the middle of the visible text when the operation occurs it will remain there (except when one reaches the beginning or end.) With this option selected, the first key press will cause the cursor to move to either the top or bottom of the visible text as a new page of text is displayed.
When this option is chosen, moving the cursor with the arrow keys off the end of a line (to the right) causes it to jump down to the beginning of the next line. Likewise when the cursor is moved past the beginning of a line (to the left) it jumps up to the end of the preceding line. When this option is not selected, moving the cursor right past the end of a line merely causes it to continue horizontally in the same line and trying to move it left past the beginning does nothing.
When this option is chosen, clicking with the mouse past the end of a line of text will place the insert cursor at the end of the text, and not in the place you clicked. This avoids accidentally adding an empty space in the middle of text, and is the default behavior of most editors.
Here the user may specify the number of steps KWrite will retain in memory for purposes of undoing entries and actions. This means that the higher the number of steps set the more memory KWrite will use for this. Setting this entry to 10 would mean that the user would be be able reverse the last ten operations, i.e. click the button 10 times and obtain results.
