138 in `select-converter-alist'---strings are the usual choice, but

|

|

442

141 system specific, but strings are always accepted).
|

142 HOW-TO-ADD may be any of the following:
|

143
|
|
|
144 'replace-all or nil -- replace all data in the selection.
|

|
145 'replace-existing -- replace data for specified DATA-TYPE only.

146 'append or t -- append data to existing DATA-TYPE data.
|

148 DATA-TYPE is the window-system specific data type identifier

149 \(see `register-selection-data-type' for more information).
|
|
428

|

152 or an overlay. In these cases, the selection is considered to be the text
|
|
442
|
153 between the markers *at whatever time the selection is examined* (note
|
|
|
154 that the window system clipboard does not necessarily duplicate this
|
|
|
155 behavior - it doesn't on mswindows for example).
|
|
428
|
156 Thus, editing done in the buffer after you specify the selection
|
|
|
157 can alter the effective value of the selection.
|
|
|
158
|
|
|
159 The data may also be a vector of valid non-vector selection values.
