[Solved] Left none / right none shorthand

[beserk1]

is there a shorthand for left none and right none?

I use it as a group, a sort of invisible bracket, instead of (), to make the formula look much cleaner

Is there another way of doing that? or do I have to stick with left none and right none?

thanks

I've never seen that before, so I'm guessing there is no shorthand for it.

Could you give an example where this is useful?

[beserk1]

Code: Select all

left none n-r right none over left none r+1 right none 

Code: Select all

 (n-r ) over ( r+1 ) 

basically is for making the formula looks much cleaner, since the n-r over r+1 will provide a completely different result, and if you use () to group it, it just clutter up the formula.

they both display the same formula, but the first one will group the n-r and r+1 with out (), while the 2nd one will group it with a traditional ().

if there is no shorthand for it, is there some sort of user-define macro or auto-correct-as-you-type feature in openoffice??

Sorry, I misunderstood what you were after.

Just use curly braces {} to mark sub-expressions in a formula:

Code: Select all

 { n-r } over { r+1 }

You can use them to separate tokens, group tokens together, or to provide an empty token:
{x}{y}

{} times 2
