How to easily double/halve/etc data in pack files?

[hellagrant]

For example building times. If you want to double building times, is there an easy way instead of manually changing each building create time? Like entering a command to double all building times.

yes there is but its been a long time since i modded some pack files and i have forgotten the exact method..but it exists...something to do with right or left clicking on the heading of columns and selecting 1 particular option that would open up a small window/menu and then writing some formula in the field there like x = 2x something something. Sorry for not being exact but i am sure the method exists to apply values to whole columns.

Just select the values you want to edit by ctrl+right clicking, then left click on one of them and choose apply expression to each cell. A small window will pop up with (x=) in it. If you want to double, type 2*x.
