Methods
- CSI_AppendBackgroundColorRGB(StringBuilder, int, int, int)
ESC[48;2;{r};{g};{b}m Append background color as RGB to StringBuilder.
- CSI_AppendCursorPosition(StringBuilder, int, int)
ESC [ y ; x H - CUP Cursor Position - Cursor moves to x ; y coordinate within the viewport, where x is the column of the y line
- CSI_AppendForegroundColorRGB(StringBuilder, int, int, int)
ESC[38;2;{r};{g};{b}m Append foreground color as RGB to StringBuilder.
- CSI_ClearScreen(ClearScreenOptions)
ESC [ x J - Clears part of the screen. See EscSeqUtils.ClearScreenOptions.
- CSI_SetBackgroundColor(AnsiColorCode)
ESC [ (n) m - Uses CSI_SetGraphicsRendition(params int[]) to set the background color.
- CSI_SetBackgroundColor256(int)
ESC[48;5;{id}m - Set background color (256 colors)
- CSI_SetBackgroundColorRGB(int, int, int)
ESC[48;2;{r};{g};{b}m Set background color as RGB.
- CSI_SetCursorPosition(int, int)
ESC [ y ; x H - CUP Cursor Position - Cursor moves to x ; y coordinate within the viewport, where x is the column of the y line
- CSI_SetCursorStyle(DECSCUSR_Style)
ESC [ n SP q - Select Cursor Style (DECSCUSR) https://terminalguide.namepad.de/seq/csi_sq_t_space/
- CSI_SetForegroundColor(AnsiColorCode)
ESC [ (n) m - Uses CSI_SetGraphicsRendition(params int[]) to set the foreground color.
- CSI_SetForegroundColor256(int)
ESC[38;5;{id}m - Set foreground color (256 colors)
- CSI_SetForegroundColorRGB(int, int, int)

- MapChar(char)
Helper to set the Control key states based on the char.
- MapConsoleKeyInfo(ConsoleKeyInfo)
Ensures a console key is mapped to one that works correctly with ANSI escape sequences.
