= Copying, cutting, pasting blocks of full lines =

Copying and pasting simple strings is one way to make use of a mark. The second
way is to cut, copy and paste blocks of full lines. In order to select a block
of lines you have to set a mark as described above in the first line which you
want to select. After that you move the cursor to the last line of the block
which you intend to select and press either ''Foenix+c'' or ''Foenix+x'' to copy or
cut the block. The block includes the line where the mark has been set and the
line where ''Foenix+c'' or ''Foenix+x'' was pressed. It is therefore possible to
select a single line.

In order to paste the previously copied or cut part of the document you have to
press ''Foenix+v'' at a position of your choice. The current contents of the
clipboard is then inserted after the current line.

In contrast to the selection of simple strings any column in a line is valid
when copying or cutting blocks. It is not allowed to cut all lines in a
document as a document has to contain at least one line even if that line has a
length of zero characters.

When you copy a block the selected part of the document is copied, which uses
up additional memory. When you cut a part of the document no additional memory
is used but no memory is freed either even though the corresponding lines have
vanished from the document. The memory used for storing the clipboard contents
is freed when the clipboard contents is either replaced by a different block or
explicitly cleared by pressing ''Alt+k''.

When copying or pasting a block it is possible that the additonal memory needed
exceeds the amount of memory still available. moreoreless detects this
situation and if it is detected allows you to save the current file contents in
a file called ''mless~''.
