Zooming - jacobslusser/ScintillaNET GitHub Wiki

Scintilla can increase or decrease the size of the displayed text by a "zoom factor":

scintilla.ZoomIn(); // Increase
scintilla.ZoomOut(); // Decrease
scintilla.Zoom = 15; // "I like big 'text' and I cannot lie..."

NOTE: The default key bindings set CTRL+NUMPLUS and CTRL+NUMMINUS to zoom in and zoom out, respectively.
