'Edit'
from the file list, the Editor will check whether enough
memory is available for editing the file. Should this not be the case, the file will
be opened in read only mode, and a message will be issued. As long as there is

opened in read only mode, because no swap file needs to be created to keep
track of changes.
2. Block operations may cause a slowdown of the Editor when working with large
amounts of data. This means that you may have to wait a little until a block has
been either, copied, cut, or pasted, if you are working with very large amounts of
text. Navigation within the Editor may slow down in the case of very long lines.

It is possible to use the Active Braille's keyboard for inputs to the PC by utilizing the screen
reader. Therefore it is necessary to install the latest Handy Tech Braille display driver for
your screen reader, which you can find on the enclosed CD.

the Active Braille's function keys must be available both as input device for the PC and for
initiating screen reader functions. The following functionalities are available to you:
