1. I am using Legacy Mode but it's behaving the same way in Map Mode and Translate mode beta 2. en-US -> en-US

The application that I am testing with is N1MM Logger Plus < https://www.n1mm.com>, a Windows native application which is written in VB IIRC Since my original inquiry, the versions of RustDesk on both the server and client sides of the connection I am testing over have been updated to the latest public release. I suspect that I did not retest with any of the modes other than legacy mode after updating -- legacy mode still doesn't work. Now, upon re-testing both Map mode and Translate mode mode beta do "work" -- "work" as in the remote application responds as expected in the case(s) that I identified although neither mode achieves this result with the unadorned simplicity of either local keyboard entry or how the AnyDesk remote desktop application (or the Microsoft Remote Desktop application for that matter) perform the identical operation (see full testing results below). Legacy mode seems to be missing the release (KeyUp) for the Q key -- that may be a reason that mode is failing. There also seems to be an irrelevant release for the KannaMode key (with no corresponding press) present as well as a press and no release for the LeftShift key. Not too surprising that the remote side might have some difficulty in deciphering what all that was intended to indicate. It is not at all obvious exactly what the extra overheads of all the superfluous traffic in the non-parsimonious cases of legacy and map modes are intended to achieve. Are there defined use cases for those three modes? If I might ask, where can I find further documentation on each of the Legacy, Map and Translate modes and the circumstance under which those modes are intended to be used? User documentation covering those modes is scant to non-existent. Just a pointer to the relevant modules in the source tree would probably be sufficient. Based on this latest testing, it would appear that Translate mode beta may be what comes closest to matching the functional behavior of other remote desktop apps. But even then, that mode still seems to consistently emit a redundant key code on release which is undesirable as it constitutes an unnecessary overhead. Hope this is useful feedback Thanks, Michael Full testing results for Alt-Q follows *For local keyboard:* *CapsLock On* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *CapsLock On* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("Q"), unicode: [81], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *Using AnyDesk (another remote desktop application which is known to work correctly with this application) to connect* *CapsLock Off* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *CapsLock On* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("Q"), unicode: [81], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *Using RustDesk * *Caps Lock Off* *Client Legacy mode* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 name: None, type: KeyRelease(KanaMode), code: 0x00, scan: 0x0000 *Client Map mode* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *Client Translate mode beta* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *Caps Lock On* *Client Legacy mode:* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyPress(ShiftLeft), code: 0xA0, scan: 0x002A name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(KanaMode), code: 0x00, scan: 0x0000 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 *Client Map mode* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: Some(UnicodeInfo { name: Some("Q"), unicode: [81], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyPress(CapsLock), code: 0x14, scan: 0x003A name: None, type: KeyRelease(CapsLock), code: 0x14, scan: 0x003A *Client Translate mode beta:* name: None, type: KeyPress(Alt), code: 0xA4, scan: 0x0038 name: Some(UnicodeInfo { name: Some("q"), unicode: [113], is_dead: false }), type: KeyPress(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(KeyQ), code: 0x51, scan: 0x0010 name: None, type: KeyRelease(Alt), code: 0xA4, scan: 0x0038
