Configuring

General Options
Selection and Clipboard 	When text or an area of the screen is highlighted with the mouse or keyboard, this is the selection. It can be pasted using the middle mouse button.
If the selection is explicitly copied using a Copy or Cut action, it is saved to the clipboard. It can be pasted using a Paste action.
When turned on this option keeps the selection and the clipboard the same, so that any selection is immediately available to paste by any means. If it is turned off, the selection may still be saved in the clipboard history (subject to the options below), but it can only be pasted using the middle mouse button.
Clipboard history 	Toggles clipboard history.
Number of entries 	Sets the number of items that are stored in the clipboard history.
Text selection 	When an area of the screen is selected with mouse or keyboard, this is called the selection. This option determines whether text selections are saved in the clipboard history. It is possible to choose between Always save in history and Only when explicitly copied. The Always save in history option is not available if selection/clipboard synchronisation is turned off ‐ in this case the selection is never automatically saved in the clipboard history. See Clipboard/Selection Behavior.
Non-text selection 	This option determines whether non-text selections (such as images) are saved in the clipboard history. It is possible to choose between Always save in history, Only when explicitly copied, and Never save in history. The Always save in history option is not available if selection/clipboard synchronisation is turned off ‐ in this case the selection is never automatically saved in the clipboard history. See Clipboard/Selection Behavior.

Action Menu
Show action popup menu 	Set the time that a popup menu will remain for if you do nothing with it.
Replay actions on an item selected from history 	If this is switched on, selecting an item from the history causes to display the actions pop-up on that item, if appropriate.
Remove white space when executing actions 	If selected, any white space (spaces, tabs, ) at the beginning and end of the clipboard contents will be removed before passing the clipboard contents to an application. This is useful, for example, if the clipboard contains a with spaces which, if opened by a web browser, would cause an error.
Include MIME actions 	If selected, include applications that can accept its type of a file name or URL selected in the popup menu.

Actions Configuration

Adding Expressions/Actions 	Click the Add Action... button to add a regular expression for to match. uses 's QRegularExpression, which uses PCRE (Perl Compatible Regular Expressions).
You can add a description of the regular expression type (⪚ HTTP URL) by left clicking in the Description column.
You can find detailed information about the use of QRegularExpression regular expressions in the Qt upstream documentation.
Edit the regular expression as described above. To add a command to execute, click Add Command and edit the command in an in-place text editing box. Double-clicking on a command allows you to edit it.
Note that %s in the command line is replaced with the clipboard contents, ⪚ if your command definition is kwrite %s and your clipboard contents are /home/phil/textfile, the command kwrite /home/phil/textfile will be run. To include %s in the command line, escape it with a backslash, as so: \%s.
Entries %0 through %9 will be replaced by the corresponding captured texts from the match pattern.

Shortcuts Options
The shortcuts page allows you to change the keyboard shortcuts which are used to access functions. You can change the shortcut to one of three things:
None 	The selected action cannot be accessed directly from the keyboard
Default 	The selected action uses 's default key. These are the shortcuts referred to in this manual.
Custom 	The selected action is assigned to the keys you choose.
To choose a custom key for the action you have selected, click on Custom and then None. Now type the desired key combination on your keyboard, as in any application.
If you define a shortcut for Open Klipper at Mouse Position pressing this shortcut will open the popup menu at the position of the mouse cursor, instead of their default position (in the Panel). Useful if you use the mouse more than the keyboard.
