|Ctrl-x||Cut selection to clipboard|
|Home||Move cursor to beginning of line|
|End||Move cursor to end of line|
|Left||Move cursor left one character|
|Ctrl-Left||Move cursor left one word|
|Right||Move cursor right one character|
|Ctrl-Right||Move cursor right one word|

Clicking with button 1 will move the cursor to that location. Double clicking will select the clicked-on word. Triple clicking will select the entire line. Button 1 is also used to select text by dragging the pointer over the text to select.
Clicking with button 2 will paste the primary selection into the line at the click location, if the window text is editable.
Clicking with button 3 will will bring up a context menu. From the menu, the user can select editing operations.
These operations are basically the same in Windows and Unix/Linux, with one important difference: in Windows, the primary selection applies only to the program containing the selection. In Unix/Linux, the primary selection applies to the entire desktop, like the clipboard.
Special characters can be entered using the Unicode escape Ctrl-u. The sequence starts by pressing Ctrl-u, then entering hex digits representing the character code, and is terminated with a space character or Enter. The Unicode coding can be obtained from tables provided on the internet, or from applications such as KCharSelect which is part of the KDE desktop. These are generally expressed as ``U + xxxx'' where the xxxx is a hex number. It is the hex number that should be entered following Ctrl-u. For example, the code for (pi) is 03c0. Note that special characters can also be selected and copied, or in some cases dragged and dropped, from another window.
