This question pops up once in a blue moon, but if your like me, getting tired eyes, and own a high resolution monitor, the font inside the SL scripting window is abit tiny and sometimes hard to read
Before changing any font in SL meant some buggery done to the client's files, nowadays you can do it with the built in options
WARNING
even though its inside the client this may have some unintended results, anything within the client that uses the same font as the script window will be effected.. as of this writing this mainly pertains to other debug functions and consoles
With normal use of SL it should only show up inside the scripting window if anyone finds different please post about it below
ok lets get started
Step 1
first thing we need to do is get the font we wish to use
SL needs a font thats in the True Type format, these are one of a few major font formats so obtaining them is no problem, you can get them from any font download site or even within your own OS.
if you grab a font from windows you have to uninstall it to a folder (click and drag) and then reinstall it so you don't loose windows being able to use the file ,... just FYI
once you have the ttf font in a place where you can find it (i like the desktop) you need to go into where you installed SL (ie c:\program files\secondlife)
inside the secondlife directory there is a sub directory named "fonts", drag your font file into the "fonts" directory, remember, write, or copy the filename we will need it in a moment
Step 2
Load up and login to SL, if you do not have the debug menus available push ctrl+alt+shift+d to enable them
goto the client menu and choose "Debug Settings" this will pop open a new window with a drop box and a value entry box, click on the drop box, it will balloon to about 1 billion options
scroll in that window until you get to the F's (its in abc order) the first setting we need to change is called "FontMonospace" click on it and the value box will read "profontwindows.ttf" change that to the name of the font you copied to the SL fonts directory , don't forget the .ttf extension
go back to the drop box and look down a little bit further and look for "FontSizeMonospace"
this is where you would change the size of the font, default is 9
Step 3
Once you have set those 2 feilds log out of SL, then log back in and thats all there is to it
enjoy!
