This will save you a little time with this constant "Single Line" info display modification.
This MOD will be in your FSX.cfg file .. located in your C:\Users\username\AppData\Roaming\Microsoft\FSX Folder.
You will currently find ...3 TexInfo's catagories... [TextInfo.1] [TextInfo.2] [TextInfo.3] These are the RED info lines that display in the upper left... each time you press SHIFT+Z.
Of course... BACKUP your existing FSX.cfg file.
You can delete the existing [TextInfo] categories...
OR... you can place 2 "/" ... REMARK references in front of ALL the existing lines of the current textinfo's. (IF you want to keep your old ones for later modification.)
Insert the following new [TextInfo.1] .. to replace your old ones.... and SAVE the FSX.Cfg file.
Use Shift+Z to turn ON/OFF the text display.This will give you the most common things we look for when flying... on a single line.
