On the Cursors tab in the Preferences screen, you can configure the appearance of EditPad's mouse pointer. You can also configure how EditPad responds to the navigational keys on the keyboard.
The appearance of the text cursor (blinking vertical bar) cannot be set in the Preferences. That can be set in the text layout configuration because EditPad's text cursor can indicate text direction.
EditPad Pro allows you to select the mouse pointer shape and style. "Standard I-beam" is the standard mouse pointer for text editing controls, typically an I-shaped beam. "Thin I-beam", "thick I-beam" and "dual-color I-beam" are custom EditPad cursors for which you can pick your own colors. By choosing colors that contrast well with the background color you've chosen for the editor, you can make the mouse pointer highly visible. "Standard arrow" is the regular Windows mouse pointer. "Dual color arrow" is another custom EditPad cursor in the shape of an arrow.
EditPad's custom pointers may not work in all situations. E.g. some remote desktop software cannot handle them. The mouse pointer may either be incorrectly displayed, or simply be invisible. In that case, simply select one of the standard pointers, which will always work.
In some editors, like Notepad, pressing Arrow Left or Right moves the cursor one character left or right and clears the selection if there is one. In other editors, like Wordpad, pressing Arrow Left or Right while there is a selection puts the cursor on the left or right edge of the selection and then clears the selection. By default, EditPad behaves like Notepad. If you turn on "arrow Left and Right move the cursor to the other edge of the selection" then EditPad behaves like Wordpad. This option is only available when the "persistent selections" option in the Editor Preferences is off. When selections are persistent, the Left and Right arrow keys always move the cursor one character and never clear the selection.
By default, pressing the Home key moves the text cursor to the very start of the line it is on. This is how the Home key works traditionally. In some modern editors, pressing the Home key moves it to the left of the first non-whitespace character of the line it is on. Pressing the Home key a second time moves it to the very start of the line. You can make the Home key work this way in EditPad Pro by turning on "Home key moves cursor to first non-whitespace character on the line".
Similarly, pressing the End key normally moves the text cursor to the very end of the line. Turning on "End key places the cursor after the last non-whitespace character on the line" makes the first press of the End key move the cursor after the last non-whitespace character, requiring a second press of the End key to go to the very end of the file.
When you turn on Auto Indent in the Options menu or in the editor options in the file type configuration then pressing Enter to create a new line automatically duplicates all whitespace at the start of the previous line onto the new line. When Auto Indent is on, there are two ways in which the Backspace key can delete this whitespace at the start of a line. If you turn on "Backspace unindents" then pressing Backspace deletes as many whitespace characters as needed to line up the cursor with the previous indentation level. That is the amount of spaces used to indent the first line before the line the cursor is on that has less indentation than the horizontal position of the text cursor when you press the Backspace key. So if you start with a blank file, type 3 spaces, type text, press Enter (which indents the new line by 3 spaces), type 3 more spaces, type text, press Enter (which indents the 3rd line by 6 spaces) and then press Backspace, then 3 spaces are deleted to line up the cursor with the first line's indentation. Pressing backspace again deletes 3 more spaces. If you turn off "backspace unindents", then pressing Backspace always deletes one character. This option has no effect when Auto Indent is off. Without auto indent, backspace always deletes one character.
If you turn on "allow text cursor to be moved beyond the end of a line", you can position the text cursor after the last character of the line. If you press the right arrow key when the cursor is at the end of the line, it will move one position to the right. If you click with the mouse beyond the end of the line, the cursor will be placed where you clicked. If you start typing when the cursor is beyond the end of the line, EditPad will automatically fill up the line with spaces up to the position where you started typing. When you do not allow the cursor to be moved beyond the end of a line, pressing the right arrow key when the cursor is at the end of a line will move it to the start of the next line. When you click the mouse beyond the end of the line, the cursor will be placed after the last character on the line.
You can choose what happens when you press Control+Arrow Up or Down on the keyboard. By default, this will scroll the text one line up or down without moving the text cursor, as if you had clicked on the up or down arrow button on the scroll bar, or as if you had rotated the mouse wheel. Ctrl+Arrow Up and Down work this way in most programmer's text editors. If you prefer to use the mouse rather than the keyboard for scrolling, you can configure the Ctrl+Arrow Up and Down keys to make the text cursor jump to the next or previous paragraph. Ctrl+Arrow Up and Down work this way in some word processors like Microsoft Word.
If you turn on "use arrow keys when the Scroll Lock key is active", then you can push the Scroll Lock key on the keyboard to scroll with the arrow keys. Pressing any of the arrow keys will then scroll the view instead of moving the text cursor. The Home and End keys will scroll to the top and the end of the file. Press Scroll Lock again to restore the normal arrow key behavior. If this option is on, then EditPad Pro ignores the state of the Scroll Lock key.
In Windows text editors, pressing the Arrow Up or Down keys on the keyboard keeps the text cursor on the same column. E.g. if you put the cursor on line 1, column 1 of an existing text file, type "abc", and then press Arrow Down, then the cursor will be on line 2, column 4. If you type "abc" on the 2nd line, it will be "stair-stepped" relative to the "abc" on the first line. If you turn on the option "Arrow Up and Down move the cursor back to the column where you started editing", then in the previous example, pressing Arrow Down will move the cursor to line 2, column 1. The horizontal movement caused by typing "abc" is undone by pressing Arrow Down. If you type "abc" on the second line, it will appear just below the "abc" on the first line. The result is that turning on this option makes it much easier to edit data arranged in columns.
"Keep text cursor in view while scrolling" determines what happens to the text cursor when you scroll the text. Normally, the text cursor will keep its position relative to the text when you scroll the text. This may cause the text cursor to be scrolled off-screen. Depending on your text editing habits, this may be desirable or undesirable. If you allow the text cursor to be scrolled off-screen, it will keep its position relative to the text. After scrolling, you can immediately continue typing at the same position. When you do so, the text will be scrolled automatically to make the cursor visible again. If you choose to keep the text cursor visible, it will be moved to the topmost or bottommost visible line when scrolling would otherwise have made it invisible. This way, you can always see exactly where the text cursor is pointing to.
By default, EditPad Pro will keep the text cursor visible when you scroll with the keyboard (by pressing Ctrl+Arrow Up/Down or Ctrl+Page Up/Down), but not when you scroll with the scroll bars or by rotating the mouse wheel. This is how most text editors for programmers work. EditPad Pro gives you the choice. Most general-purpose text editors do not allow keyboard scrolling at all.
