It certainly won't go through the gri parser without error, so you have to edit it out. The tools provided in gri-mode are `<font color="#82140F"><code>gri-option-select</code></font>' (`<font color="#82140F"><kbd>C-C C-o</kbd></font>') and `<font color="#82140F"><code>gri-kill-option</code></font>' (`<font color="#82140F"><kbd>C-C C-k</kbd></font>') to narrow in on a particular gri command, given a syntax description left on the line by `<font color="#82140F"><code>gri-complete</code></font>'. The cursor location is used to decide which gri command(s) to narrow to. <p> For example, if `<font color="#82140F"><code>gri-complete</code></font>' is used on the line `dr x a', the result will be a line like <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> draw x axis [at bottom|top|{.y. [cm]} [lower|upper]] </font></PRE> </TD> </TR> </TABLE> <p> This is the gri way of describing many commands at once. The above syntax description is a shortcut formulation for all of: <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> draw x axis draw x axis at bottom draw x axis at bottom top draw x axis at bottom bottom draw x axis at top draw x axis at top top draw x axis at top bottom draw x axis at .y. cm draw x axis at .y. cm lower draw x axis at .y. cm upper </font></PRE> </TD> </TR> </TABLE> <p> The `<font color="#82140F"><code>gri-option-select</code></font>' (`<font color="#82140F"><kbd>C-C C-o</kbd></font>') command provides easy navigation to select one of these commands. The narrowing process is governed by the cursor position. For example, to get the command narrowed down to <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> draw x axis at bottom [lower|upper] </font></PRE> </TD> </TR> </TABLE> <p> place the cursor somewhere in the word `bottom' and invoke `<font color="#82140F"><code>gri-option-select</code></font>'. To complete the narrowing process, selecting <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> draw x axis at bottom lower </font></PRE> </TD> </TR> </TABLE> <p> move the cursor to some place in the word `lower' and invoke `<font color="#82140F"><code>gri-option-select again</code></font>'. On the other hand, to get <p> <TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%"> <TR> <TD> <PRE> <font color="#82140F"> draw x axis at bottom </font></PRE> </TD> </TR> </TABLE> <p> you would have put the cursor over either the word `lower' or `upper', and invoke `<font color="#82140F"><code>gri-kill-option</code></font>' (`<font color="#82140F"><kbd>C-C C-k</kbd></font>') instead. <p> <b>NOTE:</b> you might want to practice using this example to learn how to do it. If you make a mistake, note that the normal Emacs undo works. <p> </table> <img src="./resources/bottom_banner.gif" usemap="#navigate_bottom" border="0"> </body> </html>
