Selection String Syntax

selection    = «range» ('&' «range»)*
range        = «pos» | «normal_range» | «column_range»
pos          = «line» (':' «column»)? ('+' «offset»)?
normal_range = «pos» '-' «pos»
column_range = «pos» 'x' «pos»
line         = [1-9][0-9]*
column       = [1-9][0-9]*
offset       = [1-9][0-9]*

This can be used with mate -l, Go to Line…, and the ⌘T dialog (by putting :«selection string» after the file name) — as for the latter, if a string on the find clipboard has this format, it will be the default value in ⌘T, this is useful if you have a line in Terminal like:

main.cc:32: warning: no return statement.

You can then select main.cc:32 press ⌘E and jump to Avian and press ⌘T followed by ↩ (one shortcoming is that ⌘T doesn’t show the currently open file, so it will only work if main.cc is not already the active file).
