This page describes the functions of the KRC editor which work with the selected lines of a program:

• Comment / uncomment selected text (Ctrl + /)
• Make FOLD from selected text
• Format indentation
• Motion points inside folds - warning and inserting of new points
• Signal descriptions panel - descriptions not found

Both functions are in the menu KRC and in the context menu of the editor.
▲ Comment / uncomment selected text

Ctrl + / comments (;) or uncomments the current line or all lines of the selection.

• All selected lines get the same state: if at least one line is not commented, all lines are commented; if all lines are commented, they are uncommented. Empty lines are skipped.
• A selection which ends at the beginning of a line does not include this line.
• When a fold header is selected, the whole body of the fold is commented / uncommented (also when the fold is collapsed). The lines ;FOLD, ;ENDFOLD and the parameter lines of inline forms (;%{...}, ;Params) are never changed, so the fold stays complete.
• The program frame (DEF, END, DEFDAT, ENDDAT, & header lines) is not changed.
• With Protect Folds on, single lines inside a fold are skipped - select the fold header to change the whole fold. The status bar shows how many lines were changed and why lines were skipped.
• The selection stays, so the same lines can be uncommented with the next Ctrl + /. Edit » Undo reverts the whole change in one step.

▲ Make FOLD from selected text

Puts the selected lines into a new fold: The dialog asks for the name of the fold. The name can be empty (a fold without name) and can not contain ;. The field Result shows the new fold lines, below is the number of lines put into the fold.

Option	Description
Fold name	Text shown in the collapsed fold. Empty - fold without name.
Hidden fold (;%{h})	Adds the attribute H: ;FOLD name ;%{h}. A hidden fold is not shown to the operator on the SmartHMI and can not be changed there (it is used for the hidden parameters of inline forms). Unchecked by default - a user fold normally has no attribute. The last choice is remembered.

The fold is not created when:

• nothing is selected,
• the selection crosses a fold - it contains ;FOLD or ;ENDFOLD without its pair (select whole folds or only lines between them),
• the selection contains a motion point or a part of it (PTP / LIN / CIRC, FDAT_ACT / PDAT_ACT) - see Motion points inside folds,
• the selection contains DEF / END or the first line of the program.

When the selected lines are inside a fold and Protect Folds is on, the editor asks whether the new fold should be created inside this fold.
▲ Format indentation

KRC » Format indentation (also in the context menu of the editor) sets the indentation of the selected lines - or of the whole program, when nothing is selected - by the KRL control structures:

• one level for IF / ELSE / ENDIF, FOR / ENDFOR, WHILE / ENDWHILE, LOOP / ENDLOOP, REPEAT / UNTIL, SPLINE / PTP_SPLINE / ENDSPLINE; SWITCH: CASE and DEFAULT one level deeper, their instructions two levels,
• DEF / END, DEFFCT / ENDFCT, DEFDAT / ENDDAT and the instructions of the program body stay in the first column,
• user folds are formatted with their content; folds of inline forms (motions, commands) are moved as a whole - their hidden lines are not changed,
• empty lines lose their spaces; the size of one level comes from Indentation size / mode of the editor settings (the same as Edit » Insert indent),
• when the structures are not balanced (e.g. IF without ENDIF), the status bar shows a warning.

▲ Motion points inside folds

A motion point (the fold of an inline form with PTP / LIN / CIRC) is recognized only on the top level of the program. A point inside another fold is not in the point table and its coordinates can not be edited. For safety, motion points should not be put into folds:

• Check syntax shows the warning 2511 Motion point inside another fold at such a point, with the name and the line of the outer fold.
• Make FOLD from selected text does not accept a selection with motion points.
• A new motion point (point editor, KRL commands PTP / LIN / CIRC) inserted while the cursor is inside a fold is put after this fold (also after folds nested in folds). The status bar shows a message.

▲ Signal descriptions panel

The panel of signal descriptions (long texts) shows Not found with a warning icon when no descriptions were found for the robot, instead of a loading indicator.
