Workaround for <Ctrl+F> and <Ctrl+N>

["Brian D. James" <bjames@xxxxxxxxxxxxxxxx>]

In an earlier post, I expressed a desire to have the <Ctrl+F> FINDCHANGE
function be able to detect a selected text string and to automatically find
the next occurrence of that selected text string or if no selected text was
found to display the dialog box for entry of a text string. Thanks to Barry
Hoffman for pointing out the LP_FINDSEL command to me, I was able to come up
with the following workaround to achieve the results I wanted.

First I created a macro called FIND.LX that consists mainly of the following
lines.


'extract blockstart'     /* find start position of block highlight  */
'extract blockend'       /* find end position of block highlight   */
'extract blockdoc'       /* block in document   */
'extract docnum'         /* current document   */

/* determine if any text selected and if not display the find/change dialog
*/
if (blockstart = 0 | blockend = 0 | blockend < blockstart | blockdoc <>
docnum) then do
   'LP_FINDCHANGE'

/* Otherwise, find the next occurrence of the selected text */
else do
    'LP_FINDSEL'

exit 0


Then, I modified my profile.lx file to tie this macro to <Ctrl+F> as
follows.

 'set action.c-f MACRO FIND'


These modifications achieved the results I wanted but I found that I
actually preferred to have this same functionality on the <CTRL+N> shortcut
key so I created another macro called FINDNEXT.LX.


'extract blockstart'     /* find start position of block highlight  */
'extract blockend'       /* find end position of block highlight   */
'extract blockdoc'       /* block in document   */
'extract docnum'         /* current document   */

/* determine if any text selected and if not, find the next occurrence of
the previously */
/* selected text
*/
if (block start = 0 | blockend = 0 | blockend < blockstart | blockdoc <>
docnum) then do
    'LP_FINDNEXT'

/* Otherwise, find the next occurrence to the selected text. */
else do
    'LP_FINDSEL'

exit 0


Then, I modified my profile.lx file to tie this macro to <Ctrl+N>.

 'set action.c-n MACRO FINDNEXT'


By using <Ctrl+T,N> then successive <Ctrl+N>'s I can efficiently select a
format name or variable name and then jump down through the code to the next
occurrence of that name without having to take my hands off the keyboard.
