How can I set F4 to open the selected file(s) in PSPad?
If multiple files are selected before pressing F4, they should be open in tabs in PSPad.
Thanks in advance.
Settings->Customize->Hot Keys.
Add a hotkey which runs
"C:\Path\to\PSPPad.exe" {allfilepath}
Assuming PSPPad works like most other editors and can take more than one filename on the command-line.
