Mark and region

A mark allows you to save a cursor position and to come back to it later. You can set only one mark per text window.

A region is a portion of text between the mark and the cursor. A region can be copied, deleted, restored, indented (mode C, C++, Latex, etc) or evaluated (the region must be a valid Smac expression of definition).

• Ctrl-space sets the mark at the current position. When the text is modified, the mark is updated when allowed.

• Ctrl-x m moves to the mark.

• Ctrl-x Ctrl-x exchanges current position with mark when it is set.

• Esc w copies the region between mark and cursor in the kill-buffer. It can be pasted at any current position with the command Ctrl-y or with the kill buffer box.

• Ctrl-w deletes the region between mark and cursor. The corresponding portion of text is saved in the kill-buffer and can be restored at any current position with the command Ctrl-y or with the kill-buffer box.
